Donation yearly discount steps

[Martin24]

I noticed the free updates period for Donation Edition have been improved for users that donated for a shorter time period.

5 € for 1 month is now changed to 5 € for 3 months. And 10 € for 4 months is now changed to 10 € for 6 months.

But for yearly donation it's still the same price no matter if you donate for 1 year (20 €) or 10 years (200 €).

I have a suggestion for "discount steps". I mean the more years you donate for, the more discount you get. I think this would bring a lot more donors to FFF.

This is my suggestion, does it sound fair?

1 year for 20 €
2 years for 35 € = 5 € discount (12,5 %)
3 years for 50 € = 10 € discount (16,7 %)
4 years for 65 € = 15 € discount (18,8 %)
5 years for 80 € = 20 € discount (20,0 %)

Please also add a special 10 years deal:
10 years for 140 € = 60 € discount (30,0 %)

If this would be possible to buy, I would go for the 10 years deal!
