Most people who run SRF just fill it and forget about fluid for the season.
One guy on Bimmerforums Track section even saw a race team do a flush on the race car after a few races and then put it in a street car for someone to run a HPDE!!! Not my story but there are a lot of racers on that board.
Search SRF there and you'll find a ton of info.
Let me get this straight... You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
