I do record every PT and make a timing sheet each time like J.Y. does. (cf. J.Y.'s timing sheet of PT80; click "See timing sheet here.") You can see that he never spends more than 40-60 seconds on 1 or 2 star questions.
I think LG is weird but all the games are not that difficult to solve. I did not have a clear game board to start with. Q3 took me the longest time to finish. RC was a disaster. I just couldn’t understand the last reading.
