Total Fans Gained Per Divison?

So we all know there's a chart tells you how many fans you get for end of season play offs, but does anyone have solid numbers on how many fans you get just for getting promoted thru the divisions ?

So what we're doing is estimating games played and points per division, and how many fans gained.

Conservatively, I estimate this :

Div 5 = about 13 or 15 points for promo plus win 1 of 3

Div 4 = about 15 points then win 2 of 4

Div 3 = about 17 points then win 3 of 5

Div 2 = about 17 points then win 4 of 5

Div 1 into Elite = 20 points then win 5 of 5.

This is all from memory so could be wrong.

So, roughly, (assuming you're winning most of the time) it's going to take about  5/6 games to get out of div 5; c. 6 or 8 to get out div4; about 8ish to get out div 3;at least 10 to get out of div 2: and to get to 20 points in div 1 is a minimum of 7 games, but probably 10 factoring in draws and losses; and then 5 of 5 elite Playoff wins, if you even bother doing that, means at least 15 games to get to elite from div 1.

In total, that's 45 games (lowball estimate) to go from div 5 to Elite, and that's not factoring in failed promotion pushes,  which would easily tip it up past the 50 or 60 mark.

I've noticed the fans number per game can change a lot - its been as low as 5k and high as 20k.

Assuming an average of about 8k or so, 8000x45= 360k.

However my fan count seems to go higher than 350k over the course of a multiple div promotion ; there are bonuses for promotion, right? Like 1 million for getting to div 1 and so on ? I'm not sure.

Anyway,I was just trying to work out if it's possible to actually calculate when you'll get to certain numbers of fans, and was looking for numbers on League games and not End of season playoffs (which is easily accessible, see pic related)
