Round 5 ends in three months?
You put down 8 instead of 5 in the first post HA, it should be over tomorrow

I'm far more surprised, I think it has to do with the 3 game rule.

Nor is 17, which I'll go for.

17 perhaps?

Here is the list I was talking about:

HA, can I post the list I assembled of guessed numbers?

Well, I'm insane enough to go and collect a list of all the numbers guessed so far, and how many have been repeated. So far there have been ~127 original guesses. Many repeats. 200 has been guessed 4 times

My guesses are:
150
151

Both original at that.
