    Exactly... but... hehehe its way too early to say (only did one run) i see improvements but it could be to the speed of my run... (first time i run alone in few months) and the GPS "line" looks good to me Slight smile

    Did my first OWS with the new 2.50 chipset Firmware and it worked flawlessly. So far so good.

    GPS+Galileo in running still sub par.

    During today's run in the park, during steady run on a straight alley with some tree cover, the instant pace was constantly 4:40 and 1km split came at 4:21.

    This is way off what I get using GPS+Glonass when the differences are +/- 5-10 sec between instant readings and km splits, which is completely expected due to: 1) rounding on instant pace reading displayed 2) expected fluctuations.

    20 sec difference makes Galileo setting unusable.

    4/9 failed :( Not very good percentage on success.

    Thanks for the update.  I've now had success on several open water swims using GPS+Glonass on 1 second interval, and comparisons to my 920XT (once on wrist -- differences between it and the 945 were 400y on a 2100 yard swim; once on a tow buoy - 920XT on buoy was within 50 yards of 945 on wrist over a 2100 yard swim) seem to indicate that it's in the ballpark for open water swims.  Could be tuned up a bit, but much improved over not working at all!
