Son of a gun. I must have made a mistake somewhere.

144

You make me worry I might have made a mistake. :thinking:

145

I think I know what I did wrong. When writing down the guesses on paper, I wrongly transcribed one digit of one guess. I usually double check, but I guess I forgot this time.

My new guess is 2460.
