The accelerated clock is too high. If you are going to be playing with the accelerated clock at 15 with slow gamespeed you definitely need to lower the gameclock down to 11 or 12 minutes to get the right amount of plays. You are probably getting way too many plays combined for both teams. Post a box score when you get a chance. Where do you have the USER accuracy? Post the sliders for me when you get a chance so I can make sure you have everything plugged in correctly..
