well after applying your attached patch and gathering new numbers:

    kernel32   user32      gdi32       condition (cx < threshold)
c1:  0x43       0x55        0x50        0x5F
c2:  0x23      *0x40        0x39        0x3C
c3:  0x00       0x00        0x00        0x5A

(instead of 0x41)

I could not believe it hence I debugged the whole thing again and noticed the
SafeDisc entry point analyzer was counting decoded/disassembled _instructions_,
not bytes - sorry, that was a brain fart on my side (summer heat) :|
I should have re-read my own stuff written some years ago more carefully ...

So inserting one hot-patch instruction will have no effect on majority of entry
points. The first branch instruction must be 8 instructions away.
