ok I think some of the published data may be wrong which has thrown out the calcs on the trend line as I know the original data for the 4 pots showed the only the area for the 2 of the pots.... based on 36mm pots. So as the data in the article is unclear as the title states that the PSI is load on one side of the disc, which but the SQ area is for all of the pistons (with the exception of the 4 pot which only showed 1/2 of the area it make the calcs meaning less. as I was working the force backwards as it wasn't included in the original data.
So basically as I the base data is a bit hard to understand... ignore me.
Sorry for making this all confusing I have deleted the posts...
Such things can happen.
We will work it out together and look at it from a critical point of view
