Most likely because the range is increased by 32 times in the next puzzle, and all DPs are concentrated at the very beginning of the range. Perhaps experience can help in solving the next range, but not after 5 bits.
And here is result of 3 test randomly generated keys in range 64bit and with experience from the puzzle 79.

The result is that experience helps you find the key in the current range or in the previous one, but it is absolutely useless to search in the following range that is multiple large to the current one.
In other words, in order to solve the puzzle faster you need to move from end to beginning .. first 125, then 120, then 115 and then 110))
