I do not think these cars run at 99C in normal driving. The stat would be wide open and the engine would then cool down. In steady state driving with good air flow, the stat is going to be partially open, not wide open.
Like I said, mine runs at 88 to 89 when cruising, which makes perfect sense given the stat starts opening at 86.

I am not a fan of the AC display hack and many of them are not accurate either. We prefer either actual quality instruments (after market gauges) or the use of the PIWIS or Durametric system, both of which have proven to better agree with aftermarket instrumentation setups.
We have clocked literally dozens of customer cars running well north of 205 F, even in relatively cool ambient air temperatures. Problem is that the OEM stat starts to open at 186F, but does not fully open until much higher temps are reached. You can verify this for your self by suspending an OEM stat in a beaker of water and monitoring when it starts to open, and when it is fully open.
