Average Pts per fight
1: 112.67 for each
2: 113.67 pac, 113.33 marquez
3. 115 pac, 113 marq
if the trend holds, pac will improve on the winning margin again, while marquez will stay on average. for this 4th fight we may be looking at another 115-113 average points in pac's favor (i think 116-112 for pac will not surprise me)
another "trend"
Fight 1: Draw
Fight 2: Split Decision

next logical result for fight 4? Unanimous Decision for Pac

The trend is your friend as we say in the stock market.
how would pac win?
based on trends again (moving average lang), for fight 4 estimates are:
pac total punches thrown landed 188/551 34% (ave for three fights, 160/612)
marquez 138/436 32% (ave for three fights 156/498)
pac power punches 127/313 41% (ave 3 fights, 110/270)
marquez 95/216 44% (ave 3 fights 117/301)
why does the fight #4 trend show 95 power punches for marq vs 117 3-fight average? fight 2 he had 130 power punches, but fight 3 only 100 power punches. same is true for total punches. the trend shows marquez is the one on the decline, not pacman. if any, pac has improved last three fights.
total pac punches landed: 148, 157, 176 - increasing!
total pac power landed: 100, 114, 117 - increasing!
marquez total landed: 158, 172, 138 - significantly lower
marquez power landed: 122, 130, 100 - also lower
