What is the record for consecutive seasons increasing scoring average?

[Boris]

Avery Johnson's scoring avg progression from the start of his NBA career looked like this:

1.6
2.6
4.7
5.6
8.7
10.9
13.4

I don't think it's really comparing apples to apples. I mean, how hard is it really to increase your scoring average from 1.6 to 2.6 ppg, or from 4.7 to 5.6 ppg. What Hayward is doing is far more impressive IMO.

I looked up several HOFers yesterday an most of them have 5-6 year increase streaks but it is hard to increase when you get in to high 20's, an then add, say,
Shaq.

What Hayward is doing is incredible cause nobody expected him to become this good in years 2 an 3. Most all stars are established by that time. Why I put Jimmy Butler into the discussion he has a similar rise.
