I have not heard from anyone yet a full satisfaction with new 7x5 system. Even backers of this system admits that under new system, beside other drawbacks, game often finishes too early. Why not since full match only last 7x5=35 points instead of 15x3=45 points (22 percent less). Straight match also 7x3=21 points instead of 15x2=30 points (30 percent less). Why not IBF adopt 9x5 system. It sure give enough time to player and spectators to enjoy the game and at the same time give enough breaks for commercials!!!! 9x5= 45 same as 15x3=45 9x3=27 little less than 15x2=30 (only 10 percent less) Anybody knows why IBF do not support 5x9 system?
