I think people who say speed doubling equals 50(?) ELO are talking about controlled, long time control games under controlled settings. In blitz games on the internet, where people use all kinds of hardware and software settings, perhaps changing them every game, the rating pool isn't very stable. Blitz time controls tend to exaggerate the differences in hardware speed, because of diminishing returns of search depth with respect to time. I.e., it takes more than twice as long to reach the next ply, so at some point the speed doubling will no longer give you any extra usable search depth. This affect doesn't come much into play in blitz time controls.
