Am I right on thinking for every step there is a 1 second delay on a shot, I dont actually know but I think that is the main problem with GS.
I say this because I have ran 2 macros both with the same shot rotation one with GS the other with Macrotoolkit and out of 20 attempts on both macros macrotoolkit came out a lot higher.
Could someone talk to the maker of GS and ask them ?
