No, multiple drives. I let the kids play on the games yesterday for 1/2 an hour or so, but it does seem to be a large difference. It's been very cold recently so I'd be expecting not to get a lot of range, but thought that the trip would still show the actual usage.Was that in one continuous drive? In theory that should be the total of your actual driving consumption. That will not include other uses that sap power when actually not driving along. It does seem a large discrepancy.
Will just have to keep an eye on it!
