I've got a question around the approximate expected contracts' return on investment. I'm getting a little confused with how hashing power units are used interchangeably within some of these contracts (MH/s, kH/s, GH/s etc...)

For instance, if we all agree 1 MH/s = 1,000 kH/s, then a 28,000 MH/s Scrypt contract would equate to 28,000,000 kH/s. Now, using a number of different litecoin mining calculators, 28,000,000 kH/s would generate approximately 672LTC per day which as much as I'd like to think it's true, it sounds way too over inflated for the small 0.026BTC required investment for such contract.

Am I missing something out here within my calculations? Apologies in advance if the answer is very straight forward.

Thanks
