BATTING FORMULA:

SLG = TB/AB
BABIP = (H - HR)/(AB-K-HR) (i use an internet calculator for this)

POWER:
If 5+ HRs then base power 60
If between 1-5 HRs then base power to 50
If at 0 HRs then base power to 40
(Base+(SLG100)-(.BABIP100+K%100+1B)))
Example:
(60+(.988100)-(.350100+.20100+15))) would be 88.8 power, rounded out to 90 POWER

CONTACT (easier to calculate):

.AVG+.BABIP * 100

THREAT LEVEL (a stat that ALWAYS values power hitters over contact hitters, high values often mean pitchers throw around the batter):

(SLG100-K100-15)

The 15 at the end is a luck factor, nowadays there is a 15% chance the batter could get hit with high ping or disconnect from game, killing their AB. Ive been seeing people get kicked midgame.
