    Thanks for posting.

    Currently, Gaia GPS does not include a waypoint averaging option, however, your post can serve as the official feature request for this.

    Hey Jason, funny that I find you on this site! I'd like to send you some info that deals with this. I used to be a die hard proponent of waypoint averaging, but the research doesn't really prove much benefit, so I've been using GAIA for years and am a huge fan. I couldn't find your email on the UVLT website. Could you email me so i could send along the paper? Thanks!

    Hi Donn and Jason, wow--small world! Donn could you send that info to me as well. I had also previous voted for a waypoint averaging function to be included with Gaia. I'm at jhill at vtecostudies.org

    Many thanks!

    Jason

    Wow indeed. We've started an Upper Valley chatroom on GAIA's site!

    I'll send you the data that we've been looking at. I haven't yet written up the white paper, but if you spend a few minutes with the spreadsheet you can get the gist from the pivot tables.

    Did some searching for papers on Google Scholar, but came up empty. The more I think about it, Donn, the harder of a time I have in believing that waypoint averaging isn't better. You're basically just sampling from a multivariate normal distribution when averaging waypoints. More assessments of your location should produce a better average than any one sampling draw. So put me down as highly skeptical. ;)

    I hear you, and the statistician in me agrees, but did you see the data I sent? It's pretty compelling. This is a legit testing protocol, and the hard data doesn't support our intuition. I'm not saying that I wouldn't use the feature if it were available in GAIA, but the evidence shows me that it shouldn't be a deal-breaker. Cheerio-

    Alright..I'm in your camp. I definitely expected better performance than that...and those Garmin Map76 units that we have a closet full of....wow!...that's awful. I suspect my Motorola phone does better than that, as most of the phones in your comparison did. I agree with you. I would still use the averaging feature in Gaia, but it isn't a deal breaker. Thank you for passing on your knowledge. Cheers.
