Ipad batteries last great except when the guys the match before forget to plug them back in. . For our small weekend clubs match 2-3 squads 3-5 stages, the peer to peer nature gives us great flexibility. I have been known to forget to add people, put people in the wrong squad and build stages with the wrong number of targets. This can all be fixed with limited hassle and if required a sync corrects this on the other devices. They can all be fixed when needed rather than having to go to the master etc. I realise large matches have different requirements and usually have better planning and all I was trying to say we need to keep the peer to peer for these smaller matches more flexible matches.
