CMT points for entering bills

I entered 4 bills today and the added points seem to decline for each bill a little bit.

1st bill added 5.81 points (did not enter any for 2 days)
2nd bill added 0.1245 points
3rd bill added 0.1239 points
4th bill added 0.1234 points

Interesting. So maybe it is better to add one bill every day instead?

Yes, if you can enter at least one bill per day your score will go up (hits help too of course).
