In 2ed, Rule Holding cost (x) regency and 1GB where x was = target holding value

Ruling from 0 to 1 costs no regency

In the version presented at this website, the cost is 1gb.

In the version used in RoE2 the cost is = (holding level)gb.

With some regents getting obscene amounts of regency, isn't this a good way to funnel some of that away?
