Crazy Amps Toward End of Supercharging

So right around the end of supercharging my 70D to 100%, around 238 miles, trying to get to 240, I had the amps really move around a lot for a while. It did end but is this normal at all? Is it charging different batter packs/cells at different rates to level the entire battery? They did seem to continue to decrease in number for a while (e.g. 7 became 6, 15 became 14, etc or at least it appeared that was occurring)...

I commented on seeing this too... Power Fluctuation

Did you notice the dashboard fluctuating even faster? mine seemed to. I thought this might be something strange at the low end, but when I recorded the supercharging session the other week I saw the amperage go crazy when I was at a lower SOC. Last graph on the page... P90D Supercharging Data

I asked the lead technician at a service center and he said he would try to get an engineer to contact me about it, but so far I haven't heard anything.

My non-D tends to vary by 3-4 amps at the end of the Supercharge, but if I let it continue until "charging complete" it eventually goes down to 1/0 amps. Perhaps the dual motors cause a larger fluctuation. I don't have any hypothesis as to why they would, but it's possible.

Any D owners notice the same thing?
