There's no rhyme or reason to it. I sent two sbr's off almost two months apart, checks cleared almost two months apart and then went pending the same day. I also received both form 4's on the same day. So, 6.5 and 8 months for those two. However the one that was sent in between those two came in before both of them. That one took right at 5 months. It's just the luck of the draw.
