My opinion is that air pressure is always variable uppon the use of the bike..
I use the Bridgestone's BT10 tyres and for airpressure i have 31 F and 33 R for solo and sport driving..
When i load the bike with my cases etc i use 33 F and 35 R again for solo driving. When i have also a passenger i use 35 F and 37 R.
Also always remember to adjust the preload on the bike.
My suspension is optimised for solo sport driving in all cases.
Of course have also in mind that here the temperatures are always high..
30-35 C
So..
all these are variables..
