South West XC - first test of CrossMgr

 It's no secret that I'm quite the Webscorer fan. I've talked about it a lot, and I think it strikes a good blend of ease of use, function and flexibility. Plus is undergoing constant development which only makes it better. However, for the XC races I time, Webscorer can keep up with the taps, but I struggle to keep up with getting the information I need out of Webscorer. Allow me to explain. In a single race there can be up to 12 categories. Each category has a different number of laps (some have the same number). As the leader per category finishes, all the riders in that category finish (even if lapped), but the rest must carry on. The distance between the finish line and the point to pull a rider is about 50m. On the flat. On easy grass. The call to pull a rider has to be spot on. It's a challenge, and I was stuggling. Enter CrossMgr . It's an open source piece of software written by Edward Sitarski, a cycling commissar, so he knows what he's taking on. Fir

South West XC 2022 - Round 2 - Grammarcombe

 Steve organises brilliant races at Grammarcombe, as this one was no exception. 150+ competitors, four races and three brilliant courses (under 8s, under 10s & 12s, and juniors upwards). Steve has a mountain biking weekend coming up, sign up here . Timing wise this was a passive RFID timed race, using Sportiva Event's RFID gear I've written about before. Webscorer was the software of choice. The setup was as shown below. There's not much to report on the equipment front. It all worked seamlessly. All the kit was in bright sunlight. With the previous networking kit we were using this would be enough to trigger an overheat, killing the network and therefore the readers. However, the new Teltonika modem/router and switch performed without any issues. Antenna performance is as below. This analysis is from the largest race (96 competitors).

Battle of Woodbury Common

A worryingly straightforward event, but brilliant event (by Sportiva Events ) to time this weekend. Was a bit concerned as the new EU22 (higher power) impinj speedway R420 was switching antenna significantly slower than I expected. However, needn't have worried, when used correctly. The setup consisted of two 4 port impinj readers, one EU21 spec (2W), one EU22 spec (4W). Each was running three antennas. The EU21 with is faster antenna switching was driving three linear mat antennas, the EU22 with is greater power was driving three side, circular polarized antennas. We were much more careful in the setup, leaving a good gap between the mats and the side antennas, which proved to be wise as we no issues with the side antennas interfering with the mats as I had on a previous race. Between them, we didn't miss a runner (there was over 200). However, which reader read what was quite different for adults and children. See below for the results. I am guessing the height difference bet
