Think audie asked me couple of days ago, here is what i tried to explain him :P

RANK = Points required to promoted rank = Amount of points you can hold at current rank (20 x Amount of points spent to acheive that rank) = Ratio of delegated transfered points (example)

1.) Private = 200 = 2,020 =6.5:1 (Costs 650 to send 100)

2.) Lance Corporal = 600 = 6,060 = 5.0:1 (Costs 500 to send 100)

3.) Corporal = 1,000 = 10,100 = 4.0:1 (Costs 400 to send 100)

4.) Staff Corporal = 1,400 = 14,140 =4.0:1 (Costs 400 to send 100)

5.) Sergeant = 1,800 = 18,1800 = 3.0.1:1 (Costs 300 to send 100)

6.) Staff Sergeant = 2,000 = 20,200 = 2.5:1 (Costs 250 to send 100)

7.) Master Sergeant = 2,500 = 25,250 = 2.3:1 (Costs 230 to send 100)

8.) Warrant Officer II = 3,000 = 30,300 = 2.0:1 (Costs 200 to send 100)

9.) Warrant Officer I = 3,500 = 35,350 = 1.9:1 (Costs 190 to send 100)

11.) Second Lieutenant = 4,000 = 40,400 = 1.67:1 (Costs 167 to send 100)

12.) First Lieutenant = 5,000 = 50,500 = 1.54:1 (Costs 154 to send 100)

13.) Captain = 5,000 = 50,500 = 1.43:1 (Costs 143 to send 100)

14.) Major = 5,500 = 55,550 = 1.333:1 (Costs 134 to send 100)

15.) Lieutenant Colonel = 5,500 = 55,550 = 1.3:1 (Costs 130 to send 100)

16.) Colonel = 6,000 = 60,600 = 1.18:1 (Costs 118 to send 100)

Also the inspiration buffs adds 10% to the FP also during transfer  so send 100 get 110
