In terms of tracking my quickness relative to others, autocross has this handy thing called PAX where they normalize all the times of different classes based on SCCA wizardy and many many years of data. It's not a perfect system but it gives a relative sense of how you did compared to other cars. Here's my year in autocross and PAX finishes for reference
SCCA, 3/24/19, Lone Star Park. I started the year off in March where my neighbor let me Co-drive his 2014 Camaro SS. New car to me, much heavier and a lot more power than I was used to. Horrible seating position for me (loose 5 point belts, steering wheel too far away) and a fairly bad PAX finish of 125/164 cars ("Top" 76%) (results: https://texasscca.org/2019_solo_results/tr19_2_pax.htm). Had a huge smokey spin on one run, and braked too late with a lot of understeer always. Video of fastest Run: https://youtu.be/ZBXbUh0IJsE
NTAXS, 4/14/19, TMS Bus Lot. Merkur's 2nd autocross, now with Konis and new springs and Focus brakes. I remember the car feeling a lot better but still having a lot of understeer (probably the nut behind the wheel but also a wonky camber split front/rear with 1deg front, 2.5 deg rear because of shorter springs and camber gain in semi-trailing arms). No PAX calcs for NTAXS but finished 10/16 in the displacement based "class 2", not a good result (results: http://www.ntaxs.com/uploads/2/5/5/1/25513290/2019_2_apri_14_fin.pdf).
NTAXS, 5/18/19, TMS Bus Lot. Golf R (my DD), rain that day and a huge storm that rolled through and they cancelled the afternoon runs, but I had already left because of something funky going on with my suspension. Too much car for me, so fast that I forget to brake. Terminal understeer (FWD-based AWD and a heavy foot) and All-Season rubber. Again no PAX, but finished 11/16 in "Class 3" (results: http://www.ntaxs.com/uploads/2/5/5/1/25513290/2019_2_apri_14_fin.pdf)
Equipe Rapide, 8/4/19, Lone Star Park. Driving my Friend's '99 Miata, all stock except for Konig wheels and RE-71R Tires. My first time driving a Miata and it felt GREAT! Good balance in the car and just had the feeling! Most consisent finish I've ever had, all 5 runs within 0.2 of a second (last 4 were all a 55.0XX), even with the RE-71Rs getting greasy and sliding around everywhere on my last run. ER uses SCCA classing and does PAX calcs. 1st in ES (though none of the fast guys were there) and 34/107 in PAX (Top 32%) Results: http://www.ntaxs.com/uploads/2/5/5/1/25513290/2019_2_apri_14_fin.pdf
SCCA, 8/18/19, Lone Star Park. I liked my friend's miata so much I bought my own! 4 days after purchase, at an autocross, on the dry rotted and cracked all seasons which were on it. Car slid around a lot, and I outbraked myself into a few corners. Felt kinda meh about my driving. 5th/5 in ES , 89/124 in PAX (~72nd percentile) Results: https://texasscca.org/2019_solo_results/tr19_6_pax.htm
BMWCCA, 8/24/19, Lone Star Park. Co-Driving a friend's (hereafter, "Friend #2") '99 Miata on RE-71Rs, otherwise stock. Generally good, fuzzy on the details for this event but friend #2 was faster and I wasn't feeling it. 39th/60 on RAW time. Results: https://lscbmwcca.files.wordpress.com/2019/08/2019-08-autox.pdf
BMWCCA, 10/20/19, Lone Star Park. Attempted to shove some 225s under the fenders of my miata on 16in stock wheels, epic fail. New front sway bar. Cut the rear-right tire almost to the cords in 2 runs, swapped to 205/45r16 on different wheels and ran the rest of the day. Friend #2 was co-driving the car with me, and he's always been faster. Today was no exception. Didn't drive horrible, but wasn't lighting the world on fire. RE-71Rs are magic. BMW doesn't do PAX but since most people also run in SCCA with their cars, my friend made up a PAX calculation for everyone that had a published result with SCCA, 10th/10 in Class "X" (which also includes STR cars and BRZ's, we were the only street class Miata there), 19th/33 (only 33 cars had SCCA results) in PAX.

SCCA, 11/10/19, Lone Star Park. My Miata, huge ES field (12 cars) and last SCCA event for the year. Managed to run into the leading ES driver and walk the course with him, which helped. Dropped time every run. Surface was gravely and was a big sweeper-heavy course, which rewarded a flat right foot and confidence in the grip. Balance of the car felt good, and my goal was to not out-brake myself into the tight corners and I succeeded! No fighting of the understeer, and was braking a bit earlier but not as hard and carrying more speed. Results showed it, 5th/12 in ES and a 37/149 PAX finish (Top 25%!!)
