I forgot about this thread which has a perfect example for us to compare stats, thanks to MyPerfection. Granted the info provided is for a protection paladin you can see the secondary stats drop with the same gear equipped. I will work out the exact multipliers and hopefully be able to post them before I leave work tonight...

[doublepost=1536127377,1536126158][/doublepost]Wearing the
same gear and leveling from 110 to 111 he gained/lost the following:
+5,000 raw Health (30,740 to 35,740)
+73 raw Strength (726 to 899)
-1.4% Crit (193 total crit)
-2.83% Haste (369 total haste)
-0.27% Versa (45 total versa)
-1.45% Mastery (200 total mastery)
So, it seems the higher raw value your secondary stats are the more you have to lose. If you have a M Antorus geared 110 with 250+ ilvl pieces, arti neck, 3x Azerite pieces, 2x legendaries, and a high ilvl artifact weapon you will "lose" more secondary stat percentages than if you are a 110 who is just using BfA gear.
The following multipliers can be used to figure out what your secondaries will be at 111 (rounded to the nearest hundreth):
1% Crit = 20.21 rating.
1% Haste = 19.08 rating.
1% Versa = 23.81 rating.
1% Mastery = 20.20 rating (prot paladin only, different classes have different multipliers).
