Pace display on GC

When I go to the "details" of a run, I have a handy pace graph. But it's pretty much worthless because it's always a sawtooth. Ranging from 5:00 minute miles to 10:00 miles. I totally understand that over one sample the GPS is not accurate enough to give an accurate pace. When I'm running I only look at lap pace, which gives me a decent average.

What would be nice (and easy for GC developers to do) is to apply simple smoothing to the data, so that it takes out most of the spikes in the graph and provides more useful information. I run with a 1 mile auto lap, so I can see my mile pace, but on GC I get no useful information except when looking at splits. I suppose I could set up my 405 for 1/10 mile splits, but it would be so easy for GC to apply some smoothing.

    Pace Smoothing

    I agree. GC and GTC should both allow some user controlled smooting of data. For example, many of my graphs contain trackpoints that have no 'DistanceMeters' Attributes and this is interpereted by GC and GTC as a zero speed...

    Now, I know that I didn't stop - even if the software doesn't so I should be able to delete or filter trackpoints per lap/workout that are outside a user defined tolerance (say 20%). This would be a relatively easy XML filter to apply that would remove the majority of the 'Sawtooth' features apparent on the pace/speed graphs.

    I've edited some trackpoints manually to remove the extremes for more important runs and it does make a difference to your averages as well as the usability of the data.

    Ideally, this could be a feature of the watch software too but I appreciate that this is not a trivial requirement. Which is not to say it isn't conceptually simple to do - basic runtime (no pun intended) trend analysis would allow that to happen quite effectively.
