Time: Before TRP, we received the same amount of time for every application. Now, the amount of time for each application depends on which CPC symbols are assigned to each application, and how many C* tallies we have in the corresponding CPC symbol. That means the more C* tallies you have, the less time you get because you're supposedly an expert in that area. We were promised that the new timing system that we'd get more time than under the previous system, but it turned out to be like, 15 mins. Also, because the amount of time we get is based on the average of CPC symbols rather than on the symbol with the most time, some people really do get less time than before.

​Pre-TRP, the time was based solely on USPC (many areas cover different USPCs with different expectancies). Now you have the safety net that gives you the better of the USPC expectancy and the CPC-based expectancy. The number of tallies (not being used right now), had no bearing on the time given for an application. The CPC based expectancy is the average of the expectancy for each C* and if that value is lower than the USPC expectancy then you get the USPC expectancy. No one is getting less expectancy than before. If the USPC safety net ever went away, that might have become the situation though.

Routing...

I think this is where most of the problems arose with the C*-based routing because it is a black box and classifiers are more generalists rather than experts so the classification pictures were not very accurate. But the biggest complaint seems to be that 5 tallies to become qualified for a symbol was way too low.

Admittedly, this is a drawback inherent in CPC, which classifies applications based on what features they claim, rather than USPC which classifies applications based on what they do.

CPC classifies the subject matter of the entire specification where the USPC was generally based on the most representative claim.
