We're open for suggestions and improvements!
I have one suggestion - now there's possibility to set difficulty increase rate in percent. I think that the difficulty will rise in linear fashion now - the ASIC manufacturers have a constant rate of releasing new devices that depends on their manufacturing capabilities (it doesn't matter if they manufacture them for the customers or for themselves), so the total hashrate will rise linearly (on average). There will be changes in that increase rate - if one of these ASIC companies opens new manufacturing facilities. But it will be still close to linear.
I disagree.
ASICS manufacturers will increase their manufacturing capabilities if demand stays up. When the chip and board layout are finalized, they can order parts from lots of different producers. The problem with ASICs is not to ramp up and manufacture tons of them, but to do the initial design.
