Help With Staff

I am new to iGP and am not sure what difference better staff can make, eg. a level 3 Technical Director as opposed to a level 2

any help would be appretiated 

The more advanced the staff the more accurate the information they give should be.
Although I think quite a few players will disagree with this!

I think in general it means all your staff should be better too - quicker pit stops, better fee negotiations as your team is seen as good to work with, and better health (or slower deterioration) of your drivers etc.  Or maybe that is how it will all work eventually.

I'm sure I will be corrected! :)

thanks, your probably right!
