I think 5 seconds for an 8bit binary add seems fair, so 1/12th instruction per second per 'girl', so 1000 * 1/12 = 83.33 instructions per kilo-girl per second.

I think 5 seconds for an 8bit binary add seems fair, so 1/12th instruction per second per 'girl', so 1000 * 1/12 = 83.33 instructions per kilo-girl per second. If we aren't doing 'instructions' and can get rid of binary and do decimal adds, say its 1/s, so 1k-g is 1000 'operations' per second.
