TC reads tire slip, and cuts power to compensate.
SRF, reads tire slip, and artificially increases grip by means that are physically impossible in the real world. The tire upgrade is a good example, but the tire upgrade only occurs when slip is detected.
If you want to use SRF, then sobeit, you're only hindering yourself. But if you want to make post after post about how you beat the seasonal with SRF, then people are just going to laugh at you, because no one is impressed nor proud.
I'll always look down upon it's use, and I look even further down upon those who use it while trying to justify it with an excuse.
My initial point was, you have 75PP of advantage to play with, why limit your PP and then cheat anyways? It's counter intuitive. It's literally no different than tuning your car down to 500PP, but cutting the track every chance you get. It makes no sense, you either want a challenge or you don't. If all you care about is winning, best laps, and leader gaps, then use SRF, use 600PP and go have fun.
Word twisting won't work here. I didn't say SRF was the sole reason that someone could beat my lap times, there's thousands that can do that without any aids needed, and the lap time and PP I posted aren't even impressive to begin with.
I said that your successful victories rely solely on SRF. If you think you can prove me wrong, then simply win the race, with the exact same car, same tune, same driver, same track, same field, at 520pp withOUT SRF. If you can't do it, then guess what? Your victory relied solely on the use of SRF. You can argue with logic all you want, you'll still be wrong.
