Vince said: CB said: I think there is a current error in the sheet when you have it set to auto-calculate the hit points at 75% of maximum. It seems to be auto-calculating at 82% instead? I have tested on a few npcs and it seems to be that way. I did a little testing and I think the average HP calc for NPC/Monster is correct. The average HP (50/75/100%) only effects the HP from HD and does not effect any other bonuses. Please double-check my testing if you get a chance. Thanks It doesn't give quite exactly 50% and 75% for HP based off the HD type (i.e., d4, d6, d8, d10, and d12) but instead the statistical average (I think that is the right term, I am probably wrong), which I should have realised earlier, and it is supposed to do that . I kept getting it mixed up with a normal average ufortunately, So, for example, on a d6, the statistical average is 3.5 while the normal average is 3. For statistical 50%, you get the following: for a d4, it's 2.5; for d6, you get 3.5; for a d8, it's 4.5; for a d10, it's 5.5; and a d12, it's 6.5. For statistical 75%, you get the following: for a d4, it's 3.75; for a d6, it's 5.25; for a d8, it's 6.75; for a d10, it's 8.25; and for a d12, it's 9.75. So, there is no error in the sheet, it was just me using the wrong math.
