The 6x6 puzzles seem to be getting a lot easier lately, especially the difficults. For example, over the past week or so I have solved most of the difficult 6x6s in under 2 minutes, which is very rare, and today I solved all of the 6x6s in under 50 seconds. The easy I set a new unofficial PR on (34.761) and the medium was also under 40 seconds. The difficult (which, granted, was a twin puzzle) I solved in just 46 seconds. What's going on?
I could just be getting better at speed... I don't know
