I lored about 31 high plains bouras tonight and came up with the following maximums, minimums, and averages for their hit points, strength, and resists.
Maximums
Hit Points: 653
Strength: 543
Resists: 65 / 40 / 60 / 50 / 40
Minimums
Hit Points: 576
Strength: 369 (yeah, really!)
Resists: 55 / 30 / 50 / 40 / 30
Averages
Hit Points: 617
Strength: 461
Resists: 60 / 35 / 56 / 45 / 35
I didn't really pay attention to the skill numbers until almost done for the night, so the following information is based on just 14 readings and the numbers are before taming:
Wrestling: Max - 109.5, Min - 100, Avg - 106
Tactics: Max - 103.9, Min - 96.4, Avg - 100
Anatomy: Max - 103.5, Min - 95.8, Avg - 100
I didn't make note of any Resisting Spells values, other than that it was always in the 68-73 range.
Edited to add: Just realized the two high plains bouras I tamed this morning had more hit points than anything I saw tonight. I'll throw their info into the spreadsheet tomorrow and readjust the numbers above. Grrrr. Guess that's what you do when you're rushing at 1:00 am. Sorry.
