What is the acceptable range of water temp for a street driven 996 on track days?

What is the point at which you should pit if it gets too high.

I have a dash mounted OBD II Scan gauge.
I can monitor water temp and MAP Air temp, but not oil temp.

I am starting to experiment with higher rpm (lower gear) driving and seeing water temps up 7-8 degrees hotter.
Ambient temp ranges 70 - 83 degrees.

Any input would help. Some summer track days ahead, I don't want any surprises.

I've seen water temps go as high as 210 on my car in 80+ degree weather at the end of a 25-30 minute run. ideally, I'd prefer if they were below 200. This was with a new water pump and all 3 CFS radiators. I monitored oil temp and it would regularly get to 230-240 after about 10-15 minutes. I had a 2 qt mantis pan with a oil cooler that ran up front, so that helped.

I'd say 210 is probably safe....ish....
