Tuning Huma reg for Snowpeak P35 label

Hi,

I just took out the huma air reg for Snowpeak P35 to adjust the pressure. However, the label faded. Leaving me with no indicator where to set the regulator adjustment screw at.

However, before i installed the reg, I marked the label of its lowest and highest pressure with a permenant marker and they didn't fade.

Does anyone know what is the pressure range from the the lowest to the highest on the label? If I know the range (on the label}. I can slice the min and max range to get the estimate of each pressure setting.

Thanks.
