Bingo, and we have people here like Jason Hart and Saini setting the records in national front-runner cars with perfect set-up...most of our drivers work the a computer and paper rather than in the racing industry too. It's not like the local SM's are garbage, they're set-up by pros who race cars on TV like ALMS, Rolex, and MX-5 Cup. I can only speak for myself, but most of the "fast-circle" around here have about 3-4 years of track experience and we've only been competing for 13-months, not bad for a layman if you ask me.

Those laps were 1:36.2 kyb, 1:30.6 w/d2's. I'm hoping to run 1:25's next full dry day.

Could your improvement be caused by getting more experience with the track, and pushing a bit harder because the suspension inspired more confidence?
Our tracks are very similar, short and relatively low speed from all the turns.
Everything I've seen 4 seconds below my time is tube frame on slicks. 6+ seconds would be full fender track record. I just don't see 6 seconds happening in my case. I'd be realistically happy with 2 seconds from something like xidas.
I've been planning on putting some better suspension on later this year. I hope I eat my words.

So I didn't have extra experience but for sure it did something confidence wise. The 350/250 springs were fine with uhp street tires, but were too soft for r-comps

You can also try some A-B-A-B… testing. If you think a mod dropped your lap times 4-5-6 seconds…swap back to the old parts…fine tune to suit and have at it. And look at the data…WHERE was the time being made and lost? When things get closer then things like blind testing start to make more sense IF the logger cannot clearly find zones where the improvements came from the mod. For instance you'll note that GR Motorsports magazine will do a baseline before and after testing some handling mods. You always run out of testing time but the more reality checks and followups you do, the more confident you can be that certain mods truly benefited your car in the manner expected.

Just read Grass Roots Motorsports for some reasonable testing. Not perfect of course but look at some other magazines.
GRM goes back and tests their benchmark after they have completed their main tests. Such as when they compare tires. Or coilovers. Or xxx… Andy Hollis is often involved and has won many big events in cars he developed using similar strategies.
Here is a quote from a recent tire test (my bold):
"Before calling it a day, we always retest our first tire. Did the track, car or driver get faster or slower as the day progressed? Of course, this retest is always accompanied by a bit of nervousness. If these numbers don’t match the first test, then we may have some investigating to do."
Someone claimed a six second per lap improvement after swapping coilovers. Personally I am unsure that the 6 seconds came ONLY from this swap. If there was a retest then we'd have more confidence in how much time the swap produced. There could have been some other factors. If the retest showed only say 2 seconds difference…then claiming six is likely a stretch. If six was shown by a retest, then it begs further investigation to see wassup. After all…maybe there is even more time to be found. Which can be discovered by doing the PITA stuff like this.

They are autocrossers, their track changes every time. Retesting is more important for them. They're not going to get the sustained and repeatable hours on their track to know exactly where the time is.
If I change one thing on my car and drop a full second, I could tell you exactly where it was and why.
