Interestingly, it took a shorter route home (at lower speed). Presumably it found the other route to be faster. Who knows what they do? The time recorded on-board is always a little longer that that recorded by the timing gear.

The maze timing results are suspect because search penalties seem to be missing on most runs.

Remember that the UK contest scoring includes maze search time and any touch penalties.

Another curiosity comes from running it in wall-following mode. I don’t think I can run it much faster through unknown mazes and yet the dedicated (and, lets be honest, less smart) wall followers are nearly as fast. Some lessons to be learned there I think.
