Since English is not my primary language then I'll concede that certain nuances may sometimes escape me.
Hence, the overt gist I got from the above quoted comment was that if I was so squeamish and adamant about comfort, then I shouldn't have or be driving a car with the suspension and ride characteristics of the 997.
You also go on to say... "It's your car, do as you please, but think that not only you is at risk on the road." . This comment is not only elitist since it infers that you know what's best and correct but it's also quite offensive for you infer that in not following your advice I would knowingly put my, and more importantly, other motorists lives at risk.

I looked through the manual and could not find instructions on how to set the TPMS to a given or specific baseline as the default.
The "Set" function only asks about wheel size, load and if running summer or winter tires. What I was really looking for was a way to have the TPMS accept pressures of 32/36 when hot as my defacto baseline for monitoring. As it stands with these pressures I always have a warning light on stating that my pressures are too low.
Also, I have 19" wheels so I even tried to set the TPMS for 18" wheels since these run a lower pressures. However, the warning is still there since even these have higher defaults than the 32/36 hot that I want to run.

On p 130 of my manual is a section called "System Learning," which happens after you've gone through the procedures you note. There is nothing other than the note about maintaining "tire pressures according to the units indicated on the tire pressure plate, located on the driver's side door of the vehicle," which, I think we agree, is too high.
I set mine at 33/37, and my system learned that.
(BTW, I also note a warning, "Driving the vehicle with low tire pressure increases the risk of a tire failure..". I would think 32/36 hot is too low.)
[Added comment- considering that warning, the system (Porsche) may also be telling you 32/36 hot is too low, it won't accept that. 32/36 cold may be acceptable.)
