Would be good to post some example of the deposit about for a typical solution based on various queue sizes.

In Kusama, the progression with 10% increase without changing the current signed fixed deposit is: (term == size of the queue)

Term 1: 1,333,333,332,000
Term 2: 1,333,333,332,000 * 1.10 = 1,466,666,665,200
Term 3: 1,333,333,332,000 * 1.10^2 = 1,613,333,331,200
Term 4: 1,333,333,332,000 * 1.10^3 = 1,774,666,664,320
Term 5: 1,333,333,332,000 * 1.10^4 = 1,952,133,330,752
Term 6: 1,333,333,332,000 * 1.10^5 = 2,147,346,663,827.20
Term 7: 1,333,333,332,000 * 1.10^6 = 2,362,081,330,210.92
Term 8: 1,333,333,332,000 * 1.10^7 = 2,598,289,463,231.01
Term 9: 1,333,333,332,000 * 1.10^8 = 2,858,118,409,554.11
Term 10: 1,333,333,332,000 * 1.10^9 = 3,143,930,250,509.52

Westend:

Term 1: 2,000,000,000,000
Term 2: 2,000,000,000,000 * 1.10 = 2,200,000,000,000
Term 3: 2,000,000,000,000 * 1.10^2 = 2,420,000,000,000
Term 4: 2,000,000,000,000 * 1.10^3 = 2,662,000,000,000
Term 5: 2,000,000,000,000 * 1.10^4 = 2,928,200,000,000
Term 6: 2,000,000,000,000 * 1.10^5 = 3,221,020,000,000
Term 7: 2,000,000,000,000 * 1.10^6 = 3,543,122,000,000
Term 8: 2,000,000,000,000 * 1.10^7 = 3,897,434,200,000
Term 9: 2,000,000,000,000 * 1.10^8 = 4,287,177,620,000
Term 10: 2,000,000,000,000 * 1.10^9 = 4,715,895,382,000

and in Polkadot, the deposit increase is disabled in the current state of the PR, as the increase factor is 0% -- so nothing changes from the current behaviour.

@jakoblell what do you think about this progression?
