I think one should start by understanding the Point Race first, then try and understand the complexity of having a whole second set of riders resting at any one time and variously being brought into the race on an ongoing basis.
At a live event, the main marshall usually points to the race leader every lap, so that can help enormously when one is flummoxed.
It was such a pity that Team GB didn't field anyone. JT, Mrs JT and I got to talk to Graeme Obree, who thought that bringing in Rob Hayles and someone else just for the Madison would have helped a lot in a PR sense and boosted team morale whether they won a medal or not.
