I got that number once, al lthe other times were numbers anywhere from stuff like 12 to 594734037367239376549309. It's a digital number, like 64, 255 (or 256), etc. do the math high enough and it'll reach 65355 or 65356. I think the 1 digit difference has somethin to do with it being software or hardware based D:

Edit : Look down at WW's post, he explains it much better then I could.
