True, but in that case, you'd get approximately the same level of accuracy by writing the photos without GPS data, running the GPS receiver until it successfully acquires a fix, then retroactively updating the EXIF tags in the recent photos.
Yes, of course you're correct. Unfortunately my current 6D+Lightroom solution is less clever than my old 60D+external tagger+GeoSetter ... GeoSetter could automatically write and even *interpolate* missing gps data for a certain time frame around the last fix. Lightroom cannot do that and hasn't even got a quick copy/paste function for gps coordinates.
That's why I tend to leave gps on nowadays. And buy another battery. Just what Canon wants :-p
