Somewhere in the 1-2% range iirc, definitely not a huge upgrade.
7% Conserve TP adds 0.735 TP on average (disregarding variable x-hit in VW since Conserve TP can't proc in the presence of Save TP), or 0.00569625 fTP. That's a 0.2% improvement in damage at best (no overflow). The acc difference might tilt things at times, but the Conserve TP alone certainly won't.
