For example If I am running with 1 loaded public key BSGS and for argument sake with 1 key loaded I am operating at 100 million keys per second but if I substract and load 1000 of the same key just offset by a different distance from the target key my keys per second drops 100 million/1000 (more actually) but now I have 1000 more possible chances of a collision because i have added 1000 targets.

Example

02ceb6cbbcdbdf5ef7150682150f4ce2c6f4807b349827dcdbdd1f2efa885a2630 # target

If one of these keys hits then i just add or subtract the decimal value on the right from the hex private key found convert to decimal add or subtract than convert back to hex and now I have the key for 120 02ceb6cbbcdbdf5ef7150682150f4ce2c6f4807b349827dcdbdd1f2efa885a2630

I don't think keys per second drops using BSGS, not the one I put out that Jean Luc built.
It's actually faster because with multiple pubkeys you do not have to rewalk the baby steps every time. If you are using another version of BSGS, then I'm not sure about it. But the one I use, it's the same speed, but overall faster because it doesn't have to perform and store the baby walks every time.

With Kangaroo, it probably is faster searching 1 pubkey. Let's say you shifted down 2^10; now you'd have to search 1024 pubkeys in the 2^110 range.
Avg operations of 1 pubkey at 2^120 = 2^60 (roughly) but 1024 at 2^110 = 1024 * 2^55 = 2^65 operations

if 260 pubkeys in 110bit, then how much time it will take ?

The quick and easy answer would be to look at how long it took to solve #110...roughly 2 days. You could take the 2 days and times that by 260 to get a quick and easy answer however, we know that the tames generated while searching for each pubkey would be used/valid for each subsequent pubkey. I think if one had 260 GPUs, each searching for 1 of the 260 pubkeys, and doing a daily merge/collision check, it would be much faster than the 2 x 260 days, but no way to be 100% certain.

Are all 260 in the 110 range?

16 out of 260 will be in 110bit range

Did you cut it by 800000000000000000000000000000 to drop it down one range before cutting down to 110? Could mean the difference in 2^110 versus 2^109

No cut it by 800000000000000000000000000000
exact 110 bit range 16/260 ( 2^109 to 2^110-1 )
