I simply dont have the time to put all the guesses in a spreadsheet and sort, but that would eliminate alot of the numbers....

I've Been kinda busy. But you'd only have to generate any with trip digits.
HUMMMM I wonder who's been the closest guesser so far !

I don't understand why others don't try to think this out loud, they may get an additional hint.

The numbers left are slimming down, but there is still the leading 5 and a 0, 3, 8 and 9. Could there be another 5? dunno.
Zero is questionable, since some people think it is a low digit, and others think it is a high digit.
With the range of 50,000 to 59,000 it is a decent range.
With one number being a triple, it slims it down even farther.
If I didnt miss any, that means the ranges are narrowed, and consist of somewhere between these ranges;
remember there are NO 1 2 4 6 or 7
