As i've said, in the latest v8 1-inch-decreasing is some game behaviour, as the value is stored in cms inside the file, and switching to cms will give you the same value in-game before and after using REDitor. I mean, if you see some player's height decreased by 1 inch, it's only a presentation, he's of the same "physical" height during matches.
The problem of "1-cm-decreasing in rare cases" is actually caused by Banker's Rounding, which is default in the compiler (i haven't noticed that earlier), so i've switched it to Arifmetical Rounding, and now (in v9) everything works correctly.
The next version will be probably released within a week.
Anyway, thx for reporting about D. Rose.
