- the graphic supperposition is limited
- no climbing rate
- no possibility to remove non relevant points (a stop and a sprint on a run and the graphic is unreadable)
- no possibility to cut part of a course or create a lap
for deep analysis I'ld rather to work on excel with the aim to supperpose graphics, transform altitude in climbing rate etc... As you cannot offer to everyone everything they need, this could allow us to tune our graphics.
