ScanGauge II X-Gauges for Fuel Trim

I know there are at least a few people who have set up their ScanGauges with the X-Gauges to monitor fuel trim. What's the consensus on setting this up? Does this need to be set up as four separate gauges for LTFT Bank1 & Bank 2 and STFT Bank 1 & Bank 2? Or is there some sort of rollup gauge (if that even makes sense)?

I played around with this a bit. It seems like the LTFT is more interesting to keep an eye on. The STFT moves around a lot, which is expected. I also tried setting up an A/F ratio X-Gauge, but only for the A/F Commanded. This seems fixed at 14.7. I understand it will change at Wot, but didn’t test it. I have a another car with a turbo and a/f moved around a lot more.

As a sidebar, I'm doing this only because it's interesting and not chasing down a problem. I could use EFI Live to look at this data, but the ScanGauge is more handy as a casual always on gauge.
