Thought I'd toss my thoughts into this as well, didn't really notice SRF being on, too focused on rain levels and tire management
As for Seasonal Events, this one was more interesting to me than most, good variety of PP levels, tracks, weather changes and all that, and good payout to boot.
First event I did was the TT with the C7 'Vette, threw-away the first lap just to get used to the available traction and the car itself, I usually play at Nurb' with my 568PP C6 'Vette on S3's (imagine
this), which is a little different but much faster, so after a few minor changes in line and shift-points, 2nd lap was a breeze, can't remember what time I did exactly but it was ranked like 1011th or some non-sense at that time (thurs night?), idk, I just wanted gold to gold all the events
Then Friday, I did the 600PP Tuned Car event, using
MFT's Ferrari 430 Scuderia Competizione, which is already fast enough to win on S3's I believe, but unfortunately race tires are required (

), so I just bought it some black Volk TE37's (which made it look incredible imo) and equipped Intermediate-Rain tires, got out my Android phone, streamed some "Two Steps From Hell" on Pandora (fitting music for dreary 'ring weather), and set-to racking up the miles on the 'prancing horse'. It was honestly one of my most enjoyable races since restarting about a month or so ago, music and dynamic weather most likely helped, plus I'm really starting to enjoy that Ferrari, it behaved so well in the complete-downpour that occured on the second lap, wasn't even concerned about switching tires, was too lost in bliss, found myself getting side-tracked looking at the sights around the track and checking all the little details on the car's interior view, that before I knew it the race was over and I wanted to do it again, but my back was telling me it was time to get up and stretch instead, so I saved and turned it off for the night.
Then Sunday afternoon (still doesn't feel like a Mon here, lol), I decided to give the GT500 race @ Suzuka a run with the Honda WEIDER HSV-010 since I didn't feel like buying another GT500 car at the time, and it ended up being a rather uneventful event, rain level never exceeded 25%, and it didn't really rain until the last 3 laps, stayed quite sunny, but didn't really bother me, so with a little tweaking to a setup with an aggressive diff I found somewhere on here searching (I'm more 'driver', less 'tuner'

), it was a breeze, nothing too special really, may come back with other GT500 cars n' tunes and see what happens.
And now either today or tomorrow, I'll be doing the 700PP race at Spa, which I haven't really driven much, which could make things a bit more interesting, new car + unfamiliar track + weather possibilities = ???, may end up using a tune from this thread for that particular race, planning to give Shoe's Lambo tune a try for the 600PP race again - wonder how they look on
