Walkthroughs of standard maps, focusing on SPEED.

Guys, what do you think about the standard map, Lake of Plagues?
If you play it according to the offline rules (without buying a hero with a full turn on the same day), what is the approximate time to complete it at 160%? A month? Two?

Generally, according to the offline rules, you play at 200%. But where do these scary numbers like a month come from? Or even 2? I haven't played the map, only seen it superficially, but I'll risk assuming that it's much faster. If you generate a starting save yourself, it will be even faster.
