The radio will be in sync with the TV stream, so not live but subject to delay. Has anyone seen anything anywhere as to how long the delay is? Would 5 seconds be enough or are we expecting maybe 30 seconds or a minute? Is the "live timing" actually be going to be live, or also subject to delay to sync with video and radio?

Off island it probably isn't too much of an issue, but on island the time delay from live could prove to be a problem. If they're broadcasting (video and radio of) John McGuinness passing Ballacraine, but you're sat at Ballacraine and saw him go by a minute before it's not much of a service to knowing what's happening in the race.
