It all looks and sounds good ... but, I have found that when ever I plan anything "flying wise" it never works out the way I want it....for me at least. I always had weeks at a time where I couldnt fly due to weather or planes being down .. and it makes learning commercial maneuvers harder. Instead of 3-4 flights a week, it would 4-5 flights scattered over a month. But, thats because I'm in the northeast. So, I would always need a few extra flights getting the maneuvers down cold. If your asking about this to figure out how much money you will need. I'd always take out more than you need. My best advice would be find a 141 school and get your commercial in 190hrs if your worried about getting it asap.
