What trick is that?
https://bitcointalk.org/index.php?topic=5244940.msg54629413#msg54629413Yes, old DPs can be reused if you keep old jump table, but they don't help much.
It's a good idea to use them for one next puzzle to improve chances a bit, but that's all.
Not only the next one.. 80 bit DPs extended to 90 bit range:
