Ann,

Can you confirm what you have the tracklog interval set at. If its not set
to 1 second interval then do so and take a walk around the block (after
getting a good fix). Then for a small walk like this don't try to convert
the GPX to a data layer, instead draw over the top to the alignment that
looks right. Walking usually gives jagged traces, cycling/driving gives
better results in that respect.

Hope that helps a bit.

Cheers

Andy
