Doh!!! Right you are. I had used X instead of x in my counter, but
switched mid-stream. Ironically, my tests still passed because
counting was off equally for potential solutions. Counts are right now
(I think):

500: ||||x|||||x|||||x||||| (25 toothpicks - 4*5*5*5)
501: ||||x|||||x|||||x|||||+| (28 toothpicks - 4*5*5*5+1)
502: ||||x|||||x|||||x|||||+|| (29 toothpicks - 4*5*5*5+2)
503: ||||x|||||x|||||x|||||+||| (30 toothpicks - 4*5*5*5+3)
504: |||x||||x||||||x||||||| (26 toothpicks - 3*4*6*7)
505: |||x||||x||||||x|||||||+| (29 toothpicks - 3*4*6*7+1)
506: ||||||x|||||||x|||||||||||+||||x||||||||||| (47 toothpicks - 6*7*11+4*11)
507: ||||||x|||||||x|||||||||||+|||x|||x||||| (45 toothpicks - 6*7*11+3*3*5)
508: ||||||x|||||||x|||||||||||+|||x|||x|||||+| (48 toothpicks - 6*7*11+3*3*5+1)
509: ||||||x|||||||x|||||||||||+|||x|||x|||||+|| (49 toothpicks -
6*7*11+3*3*5+2)
510: ||||x||||x|||||x||||||+|||||x|||||| (40 toothpicks - 4*4*5*6+5*6)

Thanks for pointing that out!
