Page 250, last sentence: To compute this, take the amount of money added by the tax increase (or taken away by its decrease), and multiply it by the Landholder's Income Percentage. The math in the example on the next page would need to be updated as well.
Rules issues with Landhold Maintanence in general, pages 249-251: (a.k.a Fun with math)
1) Suggest that the rules math be changed to make the previous year's modified Landhold Budget = the next year's initial Landhold Budget:
Because the Landhold Budget is based on the percentage which was taken by the Landholder the previous year, the formula breaks when the Landholder takes 0% and the following year the Landhold Budget goes to 0 C-Bills, permanently.
2) Suggest rebalancing the bonuses to the administration rolls, and/or % of Landhold Income/Budget gained/lost due said rolls:
Playing the averages, a character with average attributes, Administration +1 (worse than "Green"), who uses the following:
State Taxes: 20% (+0)
Infrastructure: 34.5% (+8)
Supplies: 15% (+0)
Staff: 15% (+0)
Defense/Security: 15% (+0)
Landholder's Income: 0.5% (no modifier),
and who rolls an average of 7 for their management roll, will increase their Landholder Income and thus the Landhold Budget by 20%/year assuming all remaining modifiers cancel, and will need to roll a -1 (negative one) on 2d6 to succeed.
Said character who starts with an average Knight's Landhold (100,000 C-Bills) will have, on average, the equivalent or better income of a:
Baronet on year 4 (207,360 C-Bills),
Barron on year 8 (429,982 C-Bills),
Viscount on year 12 (891,610 C-Bills),
Count on year 16 (1,884,8843 C-Bills),
Marquess on year 28 (~16,484,470 C-Bills),
and Duke on year 40 (~146,977,200 C-Bills),
...just in time to retire .
If the same character is instead a Veteran (Administration +5) and burns 1 edge before the roll each year (+2), the bonus goes to +35%/year. This character will have a Duke's income in ~24 years, and will be making over 130x what an average Duke makes (~16,340,000,000 C-Bills... yes, that's Billions) on year 40, all from a 10 square km parcel of land. Finally, on the character's 60th year, the character would have a personal income of over 6.6 Trillion C-Bills from that same parcel.
