My spreadsheet goes from another point of view then the system most use.
It calculates the highest possible pressure wich still has acceptable comfort and gripp. So not the minimum but the maximum, so it leaves as much possible reserve for pressure loss in time, unequall loading etc.
But If you think you can do with less reserve, you can filll in less reserve then 10% in the dark blue field.
But that means that for instance 92 psi advice can also be used 90 or 95 psi , only for 90 a little less reserve.
Mayby in time I will add something like a minimum, so if you measure that on the road , you know it still dont damage your tires if you are lucky.
Nice to see someone use my spreadsheet himself and using it directly as it is meanth.
If you ever weigh per wheel( pair) you can use part 3 , but then you have to play with the Load% instead of the reserve-adding.
Example 10 % adding is the same as using 91 % of the weight the pressure is calculated for so Load% 91%.
