Hashflare scrypt mining experiment

I am currently at 15MH of scrypt mining on Hashflare. If my BTC exchange will clear I'll make it 20MH. I got to thinking, at 20MH how long would it take to double the MH using only mining profits. This would normally be fairly easy to make a rough guess using a calculator. But, with the market going crazy like it is I decided it wouldn't be as accurate as I wanted. Plus, this way is funner. Hashflare makes a great candidate for this type of experiment because the minimum you can buy is roughly half what Genesis or Hashing24 is, and they have an "auto-reinvest" setting. This lets me ramp up mining quicker, lower entry point per MH, and the new power can get to work faster, due to the automatic reinvesting. I'll keep dropping updates periodically as things happen. My current prediction is I'll be able to buy my first MH off pure mining profits by the end of the week, assuming BTC price doesn't tank to $1,800 again.

Side note: I do also invest with Genesis mining. If anyone would like to support me there, here is my code: sxuomr
