I think I will remain sceptical until someone actually does a cardrunners style of video playing 4 tables of NL50 or something, using the SPR approach (like open raising to 7bb instead of 4bb with top pair hands, that is recommended in the book, after all). Until then I can't help feeling that it is nor practical for online multitabling.

First of all, like I said, SPR is not about raising 7BB preflop. SPR exists no matter what game you play in. Period. If you choose to ignore it, then you're ignoring information available to you. Something else might exploit it.

Second, it doesn't matter what game you can or can't raise 7BB with. I play in a live game where 7-10 BB raises are standard. The SPR will be different when I make that raise or call that raise than if the raise were 3BB. End of story.

The book talks all about how to play with larger SPRs, if that's what results. And which SPRs are good or bad, and how to get/avoid them for yourself and get/avoid them for your opponents.
