I'm sure this has been answered in here but I don't really feel like digging through months and months of posts. How current does Delta expect you to be to be competitive? I have heard 100 hrs in the last year?

I'm a ex-C-17 dude with over 1000 PIC and 2500 total. I'm 5 years non-current, got picked up by SkyWest and am about to enter into IOE, which will get me about 50 hrs of 121 flying in the E175. I'm trying to determine when to have one of my internal references send in a rec to HR. If that floats my app to the top for another look I don't want to score to low and waste the opportunity and have to wait another year. Delta is where I want to be.
