Key Performance Indicators?
Posted: Wed Apr 17, 2019 2:20 pm
I'm wondering what the key performance indicators are for the Helios and whether or not the automated tuning protocol is adequate (I would assume that it is, but I like tinkering / understanding / increasing performance).
As a proverbial tinkerer / optimiser, I've been intrigued that sometimes, my Tb/Tm DCs can be higher before the tune than after. Assuming that Tb/Tm DCs are a key performance indicator (KPI), it would seem that the subsequent tuning procedure "de-optimised" the system.
I'm aware however that it's a balancing act between the oxidation levels (lower = better?, generally indicated by La 139 -> 155?) and the Tb/Tm DCs and therefore the tuning protocol may have changed other settings that actually overall improved the performance of the system, despite the Tb/Tm DCs going down.
I'm also aware of the method to calculate the CV of the EQ beads (using plotviewer to plot 151/153 and then cluster the beads to get the CV. Lower = better and should be <12%).
I'm also plotting most / all of the data that the tuning history results contain.
So with all of that said, I guess my questions are:
1) How do more experienced users judge the performance of their Helios?
2) Do you find the automated tuning protocol adequate / optimal?
3) Do you find the automated tuning protocol can vary naturally in the settings it chooses? e.g. two identical runs where nothing has changed can result in slightly different settings.
