voltage weirdness

I have an AEM and I noticed in my datalogs that my battery voltage will fluctuate pretty wildly while shifting. Here's an example where the voltage dropped from ~12.7v to ~10.5v and then went back up. It's not consistent though, sometimes it spikes up to around ~15v. Is this normal? Maybe this is "lag" in the voltage regulator?

*shrug* I'm logging the battery voltage on a "fast" channel which is 250Hz.

Yes, although from the graph it certainly doesn't look like that rate.
