Agreed, my consideration is about separate things that might come into play:
1) Short drive time -> not enough to properly charge battery
2) Low RPM drive -> not enough current to do everything properly, including charging battery
3) Low RPM + rapid RPM gradients -> might wet and soil engine, especially plugs, making it tougher for the engine to start and run correctly
I also imagine that low RPMs might very well fail to insure proper lubrication of he head. So I am making an effort to do longer trips, and to keep engine above 2000rpm even when coasting in lower gears.
