quick question for y'all...

I have a PC with no GPU, a CPU capable of running 32 threads, and 64GB of RAM...

I've been playing with Keyhunt recently, and if I try it in address mode on a lower number puzzle I get speeds somewhere in the Mkeys/s range (I forget the exact number)... And when I try it in BSGS mode for a higher puzzle (one with a known public key, like 135) I'm getting around 880 Pkeys/s...

The problem is that I know how to calculate how big the search space is when trying to solve by address, but I have no idea how to do the same for BSGS... If the math for BSGS is completely different from calculating addresses, then is the puzzle's key range still relevant...?

Basically, I know it'll take me a gazillion years to search an entire key space either way, but I don't know if I should try my luck at addresses on a lower puzzle or BSGS on a higher one... Which one is better odds for my setup, any ideas?

Thanks.
