20 days off doesn't matter, what matters is how fast you can internalize the lessons and repeat the tasks. Trust me, any CFI will fly as often as your checkbook will allow, but that may not be in your best interest. It's a rare student who can get everything the first time in an accelerated course without repeats. It's those repeats that will eat your budget alive.

That said, I wouldn't start flight training until there's more clarity on NAI and ME3. It appears that the new white house is going to uphold the US market giveaway to foreign airlines. It's too early to tell, but there's a strong chance that US pilot job growth will be in decline as a result of open skies relaxation.
