on what grounds must you only use x% of the limit?

what proof is there that use of anything over that is a negative?

And who said this is a criteria for increases?!

I gave 1 recent example of how I recently used my credit card and 1 example of a recent limit Increase for the same credit card.

I've been there and done it with 0% deals etc -I got 'caught' during short period of unemployment....there's no rule about using 50% -though I wouldn't encourage anyone to use +50% unless paying in full -which I done for years..until I had no wages for a few weeks.
