As requested, here’s data from seven Explore matches played on either Warlord I (my gold bonus should be 250%), or Warlord III (300%).
Warlord I screenshots
Warlord III screenshots
From the screenshots posted so far, we see that Normal/Warlord I/Warlord III award 0gold values (with no 4+ matches taken) of 457, 508, and 609 gold. This is consistent with a base amount of 202 gold (yes, the 2 is there; no idea why), multiplied by 225%, 250%, and 300% – exactly what I expect from the map screen.
The 0gold values do not work out as nicely if I use the multipliers from in-battle 4+ matches. (More on them later.) If I use those numbers, the 0gold formula works out to be 1.27*$(gold bonus)-26. So you get a bonus based on your armor, but then 26 gold is subtracted at the end – the only place I’m aware of in the game, besides select spells, where gold ever has a minus sign associated with it. I’m going to call this unlikely/wrong, especially because the rounding doesn’t work out quite right.
Now, if I start earning gold during matches, what do I see at the victory screen?

The multiplier used for gold at the Normal difficulty is 380% (the 370% in that row may be roundoff error). The multiplier at Warlord I appears to be 420%. At Warlord III, I get 5 gold afterward for every 1 I earn in the battle – a 500% multiplier! Sort of.
Check out that last column of the Warlord III table. I earned 88 gold just from 4- and 5-matches. I’m actually pretty proud of that, despite it being the RNG’s work and not my own. For my efforts, the game gave me a 340% multiplier – less than what I was earning at Normal difficulty!
In conclusion, I have no idea what’s going on with the gold multipliers. The base (0gold) amounts are consistent with my armor/VIP/difficulty modifiers, but the gold earned in-match is just crazy.
