Never could estimate run time. Never saw any reason to do so (but that may be because there is no value in something you can't do, right

) Have a really tough time memorizing courses until AFTER my runs.
For me the most important thing is being able to see where the course goes "next" looong before "decision time" for turning, accelerating, slowing. This is tough in a low fast car at sites like L'burg with very confusing visual elements from a low car.
Once I know where the course goes, everything else is based on feel/experience/intuition, etc. Each run is as fast as I think is possible based on what the car is telling me unless there is doubt about where the course goes. With tires that like heat I generally assuming each run will have more grip plus I've learned where the car didn't feel "on the limit" for the situation. Between learning curve and more grip each run "should" be faster.
Since I'm a conservative driver I don't "bonsai" unless I'm convinced that I've been underestimating the car's limits. Probably due to so many events where each run had to count. (Where I started we got ONE run per event . . . which later progressed to TWO).
I pace slaloms, etc. just as a way of guestimating which gear will be needed.
My driving style is heavily based on what the rear tires are telling me in regard to grip. Understeer is always a driving mistake for me (once the car is setup "properly") since I'm responsible for knowing what the fronts can handle and driving a line which prevents understeer. My typical approach when trying to go faster than previously is to focus on more gas sooner. However, with long tight corner understeer, I may focus on entering the corner fast enough to get gentle corner entry oversteer at the slowest point of the entry so that the car rotates a bit to prevent push at the exit.
This driving by "feel" is probably a big part of why I HATE sites where the grip keeps changing from corner to corner. L'burg and Sanford are really bad for me . . . plus the rocks, chunks, sharp gravel, etc. are really hard on the car and tires.
