Inflation - When should it be adjusted?

Inflation has been the cause of much criticism from people outside the project and recently it's compounded the price slide and given people opportunity to short any price momentum. It's served it's purpose to bring liquidity in, various parties related to the project have voiced views that it should be adjusted lower to something more reasonable (including dev pool) - I think everyone is in agreement here.

The question is when should it be changed? Do we have enough trade data to forecast a sensible inflation rate? Do we need more time?
