If you have all matches you want to include into series on Android device you can create a new “series” match for them.
From the match list screen tap and hold first match to start multi-select. Then tap other matches you want to include into series. Then select “Match Series” from menu on the top. In the match settings you can select how results are grouped (by points, time or percent) and how shooters are grouped (by name or member#) and how many results you want to count for series (e.g. set 3 to take best 3 individual results out of your selected matches).
After that you can view series results on device or post them to PractiScore web site. For example – https://practiscore.com/results/html/c69a0927-b3a7-4e57-acd5-69acd986776c
The match series results could be updated with additional matches over duration of the match series. So, you can just add new matches into the series from the “Match Series” screen (aka “Build Stages” screen for regular matches) and then submit updated series results as usual from the “View Results” screen.
