Has anyone tried CDMS/Stori analysis on the QE classic? They said that it can be done on all Orbitrap instruments. Is that true?

TimsTOF people, if you inject a peptide standard for 5 times, what would your peak area %cv be?
I have been getting >20% for some peaks. Can it be the MS or it has to be the LC? The RT is reproducible.
We have a Neo, running a 10 cm 150 ID Pepsep at 300 nL/min, inject 10 uL.
