I'm not sure whether that's how I tie my laces or not as I use the "fastest" method which is demonstrated by Matt Parker on Numberphile here: https://www.youtube.com/watch?v=XPIgR89jv3Q

I think they're the same, but the method is now purely muscle memory for me and the diagrams on Ian's page don't look familiar.

Edit: Looking around Ian's site, they are different. The method I (and also Matt Parker) use is the "Ian Knot": https://www.fieggen.com/shoelace/ianknot.htm

Ian's knot is also the one I use, the secure knot is more resilient, but the fact that Ian's knot works despite being so fast and looking like a magic trick never fails to make me smile, it's an instant of glee every time I tie my shoes.
