Research: Public Order and Bribe Cost

While I was doing the research for diplomatic influence, I noticed an odd but consistent phenomenon. Bribe cost is, in most cases, directly and inversely affected by public order.

Here's a few numbers, with exactly the same town conditions except for public order. Each of these is the cost to bribe the same settlement, but with variation in public order.

• Base Bribe: 8482 -20% public order: 9582
• Base Bribe: 5782 -20% public order: 6882
• Base Bribe: 8628 -20% public order: 9728
• Base Bribe: 7734 +10% public order: 6234

So we could guess that 5% public order is worth 275 denarii, and that more order equals an easier bribe.

BUT...

• Base Bribe: 5740 +5% public order, +12 population, +3 income: 5748
• Base Bribe: 4136 +100% public order, +12 population, -456 income: 3607

These last two were pre- and post-seige numbers, so apparently seiges have a heavy and not yet understood affect on bribe cost.

Don't seiges reduce public order due to 'devestation'?

It is understandable that the faction would defect easier after they have just been sieged for 3 or 4 years!

Very strange. I wonder if it's a bug?

OK back on this. Thanks sapi for the good point -- realism-wise it does make sense that the bribe cost dropped after a year and a half (I think?) long seige. I'm going to take the seige issue separately for a bit and see if I can come up with anything.
