As an update, I drove around some with absolutely no EOC to see how many miles I was losing on the odometer. I did one commute with no EOC and got 24.0 miles on the trip meter. With my normal EOC, I was averaging 22.8 miles on the trip meter. This indicates I wasn't accounting for 5% of the miles I actually drove.

I also did another, longer trip. With no EOC, I got 105.7 miles. A few weeks earlier I'd done the same route EOC'ing the whole way and got 97.5 miles--a 7.9% difference. That route is at higher speeds, so I suspect that's why I lost more miles.

So it looks like intensive EOC "costs" me ~5-8% of my miles. Guess I need to get that kill switch done.
