Check your cylinder fill limit table. In your data logs, scroll through where you should be making the 22.5psi, and look at "mg/stk". There is also ray tracing in the data log for the cylinder fill limit table while you are scrubbing through the log. If your mg/stk is higher than the corresponding value in the cylinder fill limit table, try raising the table values so that your recorded number does not exceed the table value. That could be your issue.
