Full transparency: I have never in my life watched a game of ice hockey. In fact, I don't think I've ever seen more than maybe 3 plays of ice hockey in my life. So I come into this with zero understanding of the sport or anything about it whatsoever, so I really have no clue what the value of a hit or assist or blocked shot is. Regardless, I was confused to see when looking at the index that there's not a listed metric to tell us how much a player is accruing volume stats relative to the time they are given on the ice. I have no clue if this absence is because these volume/time-on-ice metrics are absolutely useless and meaningless, or anything like that. There are listed metrics for GF/60 minutes, as with GA/60, SF/60, and SA/60, which I think would correspond to a hypothetical "(+/-)/60", where (+/-)/60 = GF/60 - GA/60. Otherwise, there are no rate metrics that correspond to time-on-ice, really. So we can choose to calculate per-60-minutes rate statistics for the following volume stats: goals, assists, points, blocks, hits, and takeaways.
I'm going to go through each of these rates, look at the top-10 leaderboard, and compare it to the top-10 that corresponds to the relevant volume stat (I won't be showing these volume top-10s, as they can be freely accessed via the index).
We can start with goals: goals timeOnIce goals/60 min

Theodore Svatos 53 1190 2.672718
Olivers Ozols 50 1302 2.303263
William Tree 50 1345 2.231091
Jeff Lewis 21 572 2.203503

Joseph Reed 43 1321 1.952401
Tony Soprano 43 1360 1.897594
Mercedes Baylé 41 1299 1.893813
So, for the most part, we can see that players with the most goals per minute, generally, are also the players with the most goals. The standout here is Jeff Lewis, who only scored 21 goals but impressively did so in only 572 minutes on the ice, less than half of the time any other players on this list were given. The other thing to note here is that Theodore Svatos, on top of scoring the most goals of any player in the season, did so with substantially less time than anyone else in the top-10 for goals, behind by more than an hour compared to anyone else on that list. Otherwise, there's not much to learn from this, as the remaining players are within 60 minutes of 1300 minutes, so a rate stat does little to differentiate them.
At this point, I became concerned that maybe all of this was going to be fairly uninteresting, which may very well be the case if almost all players spend about the same time on the ice. To make sure I wasn't making a useless effort, I had a look at the distribution of players by time-on-ice, getting this chart:
It seems like most players sit in a range from about 1000 minutes and 1500 minutes (I'm eyeballing it), so I'm optimistic that there's enough variance that we will be able to learn a little from these rate stats.
Moving on to assists: assists timeOnIce assists/60 min

Jordan Tanner 55 1294 2.550593
William Tree 57 1345 2.543444
The only real standout here is Scott Seitz, who was the third most efficient assister despite being only the ninth most voluminous assister. However, as with goals, the trend stays the same, and there's not a huge difference between rate and volume.
Now taking points: points timeOnIce points/60 min

Our goal-scoring friend Theodore Svatos climbs high here, and despite finishing outside the top-10 in points, he ends up as the third most efficient points-scorer in the league, when you account for time spent on the ice. Once again, the top player by volume is also the top player by efficiency, something I did not expect.
Now we can get into some defensive metrics, starting with hits: hits timeOnIce hits/60 min

Daniel Grumathan 277 1264 13.146481
Ryland Murphy 267 1245 12.866953

Cameron Dallas 208 1055 11.830879
Drew Sureshot 230 1194 11.554080
Jeff Lewis 108 572 11.332303
A huge outlier here is Deep Thought, who was only on the ice for about 2 hours throughout the entire season, but managed an astonishing 12.79 hits per 60 minutes during that time. Jeff Lewis appears again as being impressively efficient at getting hits, just in the same way they were efficient at scoring goals. Lily Jin Morrow is our third outlier, but is slightly less-so than the other two. However, as with every metric we've looked at so far, the top-two in volume line up exactly with the top-two in efficiency.

Willow Soderberg-Snooks 214 1603 8.010814
Buster Knutt 167 1378 7.273079
Unlike with hits, there's hardly any difference between the top-10 in volume and the top-10 in efficiency when it comes to shots blocked. Only Isak Sogard, who ranks #9 in volume with 171 shots blocked, falls out of the efficiency top-10, replaced by either Grell Fortox or Buster Knutt, who are t-10 in volume. Between the two, Grell Fortox was substantially more efficient, achieving their 167 blocks with more than 2 fewer hours on the ice.

Unspeakable Horror 71 1395 3.054712
Curious Betsy 64 1262 3.043191
Westley Kirkpatrick absolutely dominated in takeaways this season, achieving the highest rate of takeaways per 60 minutes by a very wide margin while spending more time on the ice than just about anyone. There's not a ton of mix-up in this chart either, though Curious Betsy and Unspeakable Horror (hey! that's me!) sneak into the bottom of the list, at the expense of Might-go IA and Furious Chicken. The top-2 rule still applies as well.'
So, what have I learned from all of this? Well, overall, I think I may have been approaching this whole exercise from the wrong place. I am mostly familiar with football and baseball, where balancing volume and efficiency are important parts of understanding and comparing a player's production. I entered under the subconscious assumption that skaters would face this balance in a similar fashion to a pitcher in baseball, where a common topic of discussion is that a pitcher tends to perform worse (i.e. lower efficiency) when they pitch a large number of innings (i.e. higher volume), which is why relief pitchers, who throw far fewer innings than starting pitchers, tend to have lower ERAs (better efficiency) than starting pitchers, despite the common trend of starting pitchers being generally more capable than relief pitchers. What I found is that skaters are much more like a batter in this regard. A batter's efficiency doesn't go down when they have more plate appearances, so for the most part, the best batters will be given as many plate appearances possible, barring injuries, which means that the batter with the highest batting average will almost always be the batter with the most hits. In hockey (or at least sim hockey), as I have learned, the most efficient players will be invariably given as much time on the ice as possible, and they will maintain that efficiency, allowing them to also be the most voluminous players, in the end.
