How does Track Mode behave at 100% SoC or below 10% SoC?

I'm planing out some HPDE track sessions for spring, and trying to figure out if/how I can pull it off with my M3P. My local-is track (Calabogie Motorsports Park in Ontario, Canada), offers half day packages with three 25 minute instructional track sessions with a 25 minute break in-between. Based on having done a single session as part of a novice day last year, I estimate that I'll use about 30-35% of the battery per session. There is a 48A 240V Tesla charger at the track that I can plug in to in-between sessions, which could give me a 5-6% top-up between sessions. If I charge to 100% at the CHAdeMO station that is about 30 miles from the track and arrive an hour before the start to top up, I can easily be at 100% for the first lap to maximize my track time. So I think that I can squeeze 3 sessions in if I start at 100% and charge in-between runs, but I'll finish the day pretty close to 0% SoC.

So my question is two fold:
  1. How does Track Mode behave at 100% SoC? Regen is a rather integral part of Track Mode, so should I expect very different behaviour for the first few laps until SoC dips below 95%. Is that the case?
  2. How would the M3P in Track Mode behave at SoC below 10%? Does it go into some sort of "limp mode" making it unusable for track driving? I don't ming coming off the track close to 0% for the last session considering there is a charger on site, but there is not much point if the car dramatically cuts power. I also need to know when to bail if I can't make it to the end of the last session. The track is long (5.05km - 3.14 miles) and I don't want to run out of juice at the far end. I probably wouldn't start a lap at under 5%.

Thanks in advance!

I know it's not the performance, it's an AWD+Boost, and thus it's not under Track mode, but I find this relevant: https://www.reddit.com/r/teslamotors/comments/gnrc0n
Go see the graphs in the related images.

As the battery lowers the penalty to performance doesn't seem so bad, to a point. At 10% SOC it looks pretty dramatic to me, and I can only imagine it gets worse as it continues to lower. You might not like a 5% SOC lap...
