Close interval multiple thresholds system

We are in a digital age, and ironically, digital advancements allow less digital systems with multiple thresholds at close intervals.

A good example is the gradual increase and decrease of the ERP charges, instead of just one threshold timing that separates two periods of with and without ERP charges initially. Another not so direct example is some telcos charge by the seconds instead of minutes. These would not have been possible if done manually.

Sadly, that's about all I know about such systems. Here, I just mention one area where close intervals multiple threshold should be implemented: ... incentives cut off date, especially when the incentives are high.

E.g. before or after 17 Aug 2008 borned 1st and 5th child meant a difference in maximum matching government contribution of S$6000 and S$18000, respectively! Thus, a minute different of recorded birth between 16 Aug 2008 2359hr and 17 Aug 2008 0000hr makes a big difference.

I would like suggest a gradual increase by an amount small enough that virtually no pain would be felt, over a period of 1 or 2 months is much better. E.g. $5 increment over a period of 30 days. Thus, it will require 6000/5=1200 increments, for the case of the 1st child in the example above. This means 30/1200 = 0.025 days or 30*24/1200 = 0.6 hours or at 36 minutes interval.
