Obviously in meets you have to pause the bar on your chest, but I've found that I progress faster with touch and go. When I go to do my pauses I just figure that it's about 10-15lbs less than my touch and go (and usually I'm right).
Recently I've been doing madcow 5x5 with pause benching. It was going great until a week ago I wasn't able to get the weight up unless I didn't pause it. Should I continue progressing with what I'm doing or lower the weight and pause it?
