The SPARTAN is in RED and clearly the track is not as good as that of the 920XT. The SPARTAN seems to have me swimming backwards in places which is clearly wrong. I may be bad but I’m not THAT bad.
The 920XT’s algorithm seems to take notice of fewer GPS points (or the SSS takes note of more). Whichever way you see that happening I just know what the track should look like and the Garmin is quite a bit closer to today’s reality and their algorithm works better, IMO.
The Garmin had me doing c1600m and the SPARTAN SPORT had me doing c1800m. I probably swam 1550m.
I’ll keep this post short as there is not much more than can be meaningfully said.
