1 > 80 key not 80 keys [single key] [random mode with 4.7 Ekeys/sec] [4300000000000000000 keys/sec] [3BACAB37B62E0000 keys/sec][ whole 65 range in 1 sec]. now compare with bsgscuda  
        with reference key in range 49dccfd96dc5df56487436f5a1b18c4f5d34f65ddb48cb5e0000000000000000:49dccfd96dc5df56487436f5a1b18c4f5d34f65ddb48cb5effffffffffffffff.  let me guess 3080 took with full
        optimization around 17 second but keyhunt took just 1 second. even i have to reduce k and n value to reduce speed for this  Grin.
2 > do your research and than find how many keys you will get while doing 120 to 2^40 divisor [lol]. if you will load 2 keys, you will make keyhunt speed half and what about billion keys . speed will be just like your mind
       processing to understand my answer.
 
4300000000000000000 it is 2^61.89. so whole 65range( i think you mean puzzle #65 with range 2^64bit) need 4.28 seconds
I don`t have 3080 card but i think speed will be around 1400Mkeys x BabyArraySize
windows10 eat 20% of GPU memory so 3080 should have 8192 free memory, so we can use -w 30
Totaly 1400mkeys = 2^30.38 and baby array x2 = 2^31 and full perfomance = 2^61.38 and to check full 2^64 need 6.14s
Only Kangaroo can solve keys faster then bsgs or keyhunt or whatever.
Bsgs cuda created only because i didn`t find bsgs for gpu (maybe it useless app i don`t know)

i am not arguing on your math but if you have time and hardware please just try to do research on keyhunt [CPU+memory ] and by the way i appreciate your programing skills toward cuda its really impressive and wish some day you will enhanced it more to overcome 120 and by the way i know one guy who is running it with 9+Ekeys/sec [yoyodapro].

and just to let you know i figure out way to reduce  [120bit] key until 90bit with 186384565 keys & guaranteed 15 keys are in range. but with divisor you can get only get 1 key out of  1073741824 if you want to reach 90bit.
i loaded all keys in keyhunt and i am trying my luck but on other side i was hoping if we can figure it out how to load multi keys with cudabsgs . so i will keep busy my 3080 for that as that one is just sitting idle now.
