Should be - what are your other scores? Perhaps there is a glitch in the program.
I don't understand - and this isn't directed only at you - the purpose of having a handicap, but not getting a USGA handicap. If the USGA isn't certifying it - then it doesn't mean anything.
I think it's cost. There's a bunch of free handicap systems. I kept mine on the GLMS for awhile, but our club requires a GHIN handicap for most events. So I get to pay for that. Plus, the systems don't talk to each other, so I got to print out my scoring record and enter it, score by score, into GHIN. Gotta love it.
