There are two kinds of France nowadays in regard to PBP.
You have the randonneuring heartlands, Bretagne, North and Ile de France. Riders there are aware of the changes in PBP, they do their brevets every year and keep on top of things. They know that PBP is an international event.
I have been mistaken for a Norman or a Fleming at Semaine Federale, those being the biggest and tallest of the French. There are cultural links with the area I'm from, so it's understandable. So the Norman controls, Mortagne and Villaines are my favourites. Villaines is actually very badly laid out. But they provide a map of the site, and a couple of children to guide you through the maze.
I do like Brittany, and the great virtue from an organisational point of view is that there are good, non-toll, roads. There is a mobile volunteer element. The guy with the microphone, who the French term an 'animateur', turns up at various points on the route. It's interesting to disentangle the core functions from the control-based ones.
The electronic timing is a core function, connected to HQ. The stamping of the cards is a local function, carried out by local volunteers, and there isn't actually a link between them. I arrived at Loudeac wanting to know when the first group would arrive back from Carhaix. That information wasn't available, and I cobbled together an estimate from the tracking, and a knowledge that Zigzag had been doing well.
The obvious answer to the appetite for feedback is to put the time in hand on the tracking. Those with a smartphone can then use that. Those who want to use other methods can.
