I commented yesterday on the Contrail J333 page noting that the thrust data there starts with two data points, both at T=0, but with the latter having a non-zero thrust. After adding a check for this and other related issues I've found myself cleaning up a number of other files, below.
Specifically, I found these types of issues:
"Non-zero thrust at T=0": This is either the issue referenced above where there are two T=0 samples OR the first sample point has significant non-zero thrust at T=0.
"Ignition at T=####": These are data files where there are one or more initial samples with "negligible" thrust (0.1% of the motor's avgThrustN).
That latter point is arguably not an issue. It's just a judgement call I've opted to make for thrustcurve-db to remove samples that don't contribute significantly to the thrust data.
Lastly the sample data for the I747-HP motor is... weird.
