How exactly does the price reduction stack (Soldier's cost reduction General & Gold Banner)?

Archangel

Own: 0 *

Buy Price (x1 * ) = 7,500,000 [default price]

w/ Gold Banner only = 7,125,000 [5% discount]

w/ Penelope LV4 only = 7,200,000 [4% discount]

w/ Garlan LV4 only = 7,050,000 [6% discount]

w/ Darius LV4 only = 6,750,000 [10% discount]

Case 1: w/ Gold+Penelope = 6,840,000 [8.8% discount]

Case 2: w/ Gold+Garlan = 6,840,000 [10.706...% discount]

Case 3: w/ Gold+Darius = 6,412,500 [14.5% discount]

Why they are not 9% (missing 0.2%), 11% (missing 0.293...%), and 15% (missing 0.5%) for each case respectively?

* Note: It also happens at each subsequent buys.
