Hi-
This appears to be a rounding / trucation error.
So, should we not initially add one to fix this?

00000111 +1 => 00001000 shifted=> 00000001
123:  01111011 => 01111100 => 00001111 10000000  +  00000001  11110000
=>  00010000 =  16
123 => 7B +1 => 7C /8 => 0F 80 + 00 18 => 11 70 discard low byte=> 11 = 17!
235 => 33
