Re: RBU Release thread
I'm going to repost what I posted some time ago when questioned about this. Hope it helps:
With each new version of the game, the sim engine calibration changes based on what's happened the past few years in MLB. This is done (I believe) to keep their ratings scales from shifting too much. There's been a significant uptick in HR numbers the past few years and I think this was finally reflected in the this past year's game, because the previous scale was producing way too few HRs in my 2021 testing.
My mind's not on it like it was when I made the adjustments, but I recall being very surprised myself at how low the HR ratings needed to be to reproduce the same outcomes as before. For some years, the swing was a many as 10+ points, and while this was alarming, when I created my 1983 roster based off the new scales, it worked perfectly in the sim engine, and the subsequent franchise season I played out was fine.
I test meticulously; when I create a test roster I will sim as many as 10 seasons and average out the results b/c there can be quite a bit of variability even between individual seasons. The whole thing is quite a headache. And I have no way of testing all historical eras at once, so certain years might be off, as I suspect the most recent seasons (2016+) probably are, but since my utility is primarily for historical roster makers, I'm not as concerned about that.
I would still recommend when you create a roster to sim out some seasons and note HR totals (I use avg HR per team as a metric) and compare with MLB totals for that year. If it's off you can add or subtract a few points from the HR/9 ratings.
All of this is one reason I have to readjust with each new game release, but is also why I recommend only using the RBU version that corresponds to game release you're playing.
