Even allowing for overestimations are we comparing two distance casts here? I was told somewhere on this forum that on a full blown 5WT distance cast tip speed might reach close to 100mph and the haul was still an unknown. 10m/s is 22mph which I’ve always thought was low, which I think is why we measured mine to prove me wrong (again!)

It would be good to find a way to get some line speed numbers out of interest. Maybe we could suspend a rope tight between a few posts at tip path level, marked at regular intervals? For example that red and white striped safety tape might work? And then zebra mark the line. Perhaps there is something better we could attach to the line other than a flag?
