I think the OP should be given the benefit of the doubt. He has the benefit of knowing the area well and is familiar with all that goes on above him. Secondly, it is not wise to rely 100% on tracks shown on the various tracking sihets. They are not updating/recording data by the millisecond and there is a tendency to extrapolate when showing tracks, a sort of "join the dots" thing. If
beamender99 says it was unusual, then I think we should accept there was probably something unusual. After all, he was on the scene and I don't suppose any of us were.
I have just looked at the historical track on Planefinder and this show the aircraft going round the Ockham stack 3 times.
Cremeegg qutoed FR24 as showing 2 circuits. I neither know nor care which is accurate but it does seem to prove my point about relying on tracking sites to be 100% accurate. It may be more informative to use Webtrak:
