# Pressure range data

I am actively collecting pressure range data.

All the data is stored here: <https://1drv.ms/x/s!Aml8i4Jd6crCkTerfXD_1zsIxg3A?e=7HqT7T>

Key notes:

* I am not good at measuring IAF, so I believe my measurements show higher IAF than is accurate.
* I am confident in my max pressure measurements.
* I assign inventory IDs to my pens so that I can track them over time.
* Remember that a given model of pen has individual units that can have widely varying IAF and max pressure values.
