Tire pressure before and after (actual cold pressure was 2.06 Bar, as it the tires cooled to ambient 26 deg C before going on the track) - snowflake is cold, sun is hot:

Edit (looked):
2.45 (35 psi) doesn't look too bad, I think. And is not completely out of line with what Yokohama recommends (32-34 psi).

I know what site you are mentioning. They are too conservative with their tire pressures and it is not an official site of Yokohama Japan. Just an article of an unknown guy working for Yokohama Australia. In fact by having a pressure of 2.1 cold, your tires are deflated and you are losing 1-2 runs to hot your tires. Can you do a professional warm-up cycle in GP-Strecke like racing drivers doing before the race? I don't think they'll let you do this in tourist fahren days in GP-Strecke ...
I remember there was a video of Tetsuya Yamano who was responsible of designing the new RE-71R tire for Bridgestone. In fact this tire should be called the Tetsuya Yamano tire. He is one of the top racers in Japan and he was testing these tires using also a GT86/BRZ car. He was mentioning that it is pretty fine to run the tires with the recommended manufacturer pressure (2.4 bar cold). Modern high performance tires can handle temperature quite well and it is just fine for 5-6 rounds in a small race track.
Personally, I trust much more Yamano than some random guy publishing BS articles on the internet. Besides, neither our cars are racing cars nor we are racing drivers . The whole idea is to just have some fun with our cars either on street daily or more rarely on race track
