The noise level is approximately 0.6-1 %, thus, a basepeak cutoff of 1% discards many FP FA combinations,
Some FA compositions are lost due to this cutoff, but singlechainident or lower cutoff leads to many FP combinations.

There were no position rules defined (only spectra of 36:1 are available to develop these rules, and the chain fragment intensities behave rather contrary in two samples)

All analytes are found, there are no FPs reported.
Not all FA compositions are found, but there was never an incorrect composition reported.

There are no MS/MS available in biological samples.
