Record is correct, but that record will now stand for all time, as the new weight divisions have come in.
There's no fixed percentage a bench shirt gives you. Some people get less than 5% carryover. Some get as much as 40%. It depends on the shirt, depends on the lifter's skill, depends on limb lengths etc. Long armed lifters don't seem to get as much assistance, as the triceps sticking point covers longer range of motion. The shirt doesn't help you much with that.
The other thing you need to consider is that comp bench presses are pauses at the chest, no butt raising, no feet lifting, no head lifting, no belly benching.
A paused press is on average about 5-10% less than your touch and go.
