Not saying that's bad or wrong, just saying by default the TC value with trim centered is 29-30%.
Andy can comment on it with the detail specifics about this but I know what I said is correct, I hope.
Your right. 29 nails it here. I was using 24 and thought it was working. That could have been an accident waiting to happen.
