New to YSM - clarification needed

[KeepTrying]

I've just opened an account with YSM and set up some listings.

What I want to know is this:

How accurate is the 'est.clicks' in relation to a particular 'max.bid'?

Is it correct, or totally incorrect?

By what % is it in error eg. 10% over, or 30% less than the true figure.

It's a figure that's critical to determine whether any money can be made on YSM.

Thanks
