Dont take it to heart Derick, its not have a go at Derick day, is it? i,m just giving my opinion on what I see, and if you feel that by going back over your work and that gives you more satisfaction because you feel you have done a better job by doing this, then fair play. The only benefit imo that can be gained by your method is, it will dry your carpets a little better.
"if you are removing more after you have , pre sprayed , agitated then extracted with your t/m i can only assume you are doing some thing wrong, or your t/m isnt working "
"like i said geoff, each to there own, as for doing something wrong, its really difficult to prespray agitate and then extract so maybe i need more practice, after all, this carpet cleaning lark really is hard to master. and i've only been cleaning for a year and a half so ive a long way to go before i get good at it.

Derick, take a look above, I also suggested your t/m may not be working :
