Got a RAM mount so I can keep an eye on my phone while I rode. When the Zero app is running, I noticed a couple of disparities: The speed displayed on the app is different from the speed on the dash; I attribute that to the app collecting its data via the phone's GPS. However, the app was also showing a consisted 2% higher rate of charge than on the dash. Anyone know why that should be? If the dash is displaying 50%, and the phone is displaying 52%, should I assume the actual value is 51%? Just curious... that 2% isn't going to make any difference in when I hit "panic mode" or not...

The speed on the phone doesn't come from the GPS but from the motor/computer. I had a bike on a paddock stand to do some testing and even with the belt disconnected it would display a speed.
-
Okay... then I have no explanation for why those numbers don't agree either, then.
-
I'd understand if the phone app showed readings with a delay with respect to the bike instrument panel. But I don't know how to explain the bike showing that I use about 60 Wh/mi trip and lifetime, while the phone app shows about 90 Wh/mi.

With speed - I know on the older "2013" dash we can set different ratios for gearing.
I doubt that value is communicated back to the bluetooth central brain because there is also a "drift" in Odometer which gets bigger (or smaller) as you "calibrate" the Speedometer hardware between the APP and the DASH.

The app will read 5% when the dash reads 0%. The dash will never show 1% it just skips it.
So at low SOC it's really 4% off to protect you from getting yourself stuck somewhere. Or to leave some in reserve
each 25% the dash gets one percent closer to actual
so at 50% on the dash its really 52% and by 100% its accurate

Yeah, I found this out the exciting way.

This is information that would have been really good to know about three weeks ago. Thanks for the info!

Completely meaningless thing I've noticed on my bike: it NEVER shows me 81%. Every morning on my ride to work I'm in the 82-86% range at the start of a long gradual downhill, so I'm using energy slowly for a couple of miles. The SoC indicator inches down very slowly...except when it gets to 82%. Instead of showing me 81% next, it jumps right to 80%. It happens every single time, so it's clear there's just no 81% on my bike. I wonder if every Zero does it or if my bike has had an 81-ectomy.

Mine does the same, also it jumps from 62% to 60%
I'm guessing its rounding something somewhere else which causes this jump.
