Yes. 50% is a good goal to look for to lock in a profit. The TastyTrade guys usually buy options ~45 days until expiration and roll to the next month at 21 days until expiration. 
  
 Your option you sold in a spread usually doesn't get excercised, but if it does, you just make max profit. This is if you're buying a call spread.  
  
 The idea of buying a call spread is that you're reducing your risk amount, but you're also capping your max profit.

Nice I'm assuming 45-21 is ideal for selling covered calls too
