Keep in mind the pre-lap has had about 2 weeks of thermal interface curing. The Post lap were mins old. So over the next week my temps will probably drop a few more degrees as the TIM cures. But here are my results of lapping a 2500k. It was definitely worth the effort. Every chip I've owned I've lapped the last few years, it's always worth the effort imo.
