It shows ROI time table. with an increasing difficulty.
I didn't want to list all the data as it was a lot of data... but here you go:
The numbers on a calculator are so far off you may as well scribble numbers on a wall and throw darts at it. There is no way to estimate difficulty or LTC price that far out so all those numbers are trash.
The reality is, an ASIC miner in this space as a 3 month ROI, a GPU rig will cost twice as much and have more like an 8 month ROI
I agree it is too far out to tell, which is why i'm hesitant to buy an ASIC. Who knows that the market would bring in that time frame. So you would say ASIC over a GPU rig? Even if the ASIC is a 4 month wait?
