Observations

The matter of fact is, scrum masters are so dumb that they add up points incorrectly. Points are proportional to the logarithm of time.

The right formula for the time (in hours) of one case is h = 3* 2n/2, where n is the number of points. Accordingly, the number of points for a given period of time (in hours) is log2(h/3)*2 (where h is time). One human-month is 12 points. One human-year is 18 points. One human life is 33 points (approximately).

10 1-point items is 30 hours. it's not the same as one 10-point item (obviously).

The right formula for adding up points p[1]..p[n] is:

2*log2(Σi=1..n(2p[i]/2))

Any questions?
