ASIC chip advancement rate

[Mines closed]

!BTC hello fellow miners ! BTC!

new to the site, really enjoy everyone's snarky insight.

my question is: over the course of a year I have noticed the speed of ASIC mining units increase nominally...
 
Does anyone have a clear idea of the potential processing power and some way of calculating future hashing rates of Application Specific Integrated Circuits ?
 




Thanks in advance to anyone who can help.
