45 minutes for me. A brilliant challenge. Taxing, with lots of pauses, but never truly stumped. Just right! Thank you for creating this puzzle.

It should flow nice and smoothly unless you make a mistake right at the beginning that only reaches a contradiction near the end!!! I solved it about 3-4 times as I couldn't believe how early my mistake was. Doh!
