A minor detail... I just saw on your profile that your last login to the main site was 9/04/2019 @ 01:20:44 PM, but you posted a review today. Have you really been logged in all that time? Just wondering...
It's actually supposed to be "4HAND" (a lame pun on 'forehand'). The binary value 0100 is equivalent to 4 when expressed as a base-10 number. The other characters follow the standard binary-to-text translation, so I can see how the binary-to-decimal throws a wrench in things.
