LTM Updated
Mark Liversedge has updated LTM and posted a beta patch to the mailing list.
The biggest improvement from my perspective is the ability to see your various power ranges for a time period. For instance, this is a plot of all my 5 minute power from 2008. You can see there being an improvement from March until September when it drops off again. Of course I may not have been doing 5 minute efforts during that time where the watts are low, but this still tells you very well what you were doing for that time.

As well for people who just like to see lines all over the place, you can select multiple metrics and have something looking like your 2yr old’s painting.
