Mass repeating bar code readers is easy, and with wrist band based marks the runner is easily able to speed it up.
FRA should say what they are trying to achieve, leave the RO to find the most expedient way to achieve it, numbering systems, marshalls etc, with reference to size of field, course and conditions. For a parkland race up and down one hill, the rules are a sledgehammer cracking a nut. Badly.
Those numbering/ marshalling sections of the "old version" were one of the first things to irritate wynn ( other than not recieving them long ago before they first became tablets of stone, leaving Her to discover them recently). Point was they were sending her ROs to come and see how to do it "properly" only to outlaw some aspects of what she did, without even asking her first. The drafts have then changed without version control, so hard to know what or when was updated since or whether she can comply with modified.. There is a newer version under consideration, but not by such as her to comment. Shambles is the word that springs to mind. Such as wynn ( and witton) by should have been invited to sit on the RO side of the " virtual" table, with FRA committee represented the other to balance the views that went in, and at least guarantee all present races did not have a problem.
