How much gold do champion kills give on Proving Grounds?

Tl;dr - Gold is distributed diffrent in Proving Grounds than in the Summoners Rift. Focusing on killing dominating players are more rewarding than in other League of Legends game types.

I played ARAM moment before and I do some math based on my observations. I can't be sure about gold per kill but I will be sure about killing players and this should show me some rules behind it.

I also make an assumption that Riot based values on V1.0.0.120 Summoners Rift gold per kill values. With this you can see some pattern here.

• 1st kill ? 47% ~ 140 gold - which confirm @Julian G. post.
• 2nd kill ? 52% [+5% Change]
• 3rd kill - Killing killing spree player is 237 G comparing to 408 (58%) [+6% Change]
• 4th kill - Killing rampage player is 308 G comparing to 475 (65%) [+7% Change]
• 5th kill ? (72%) [+8% Change]
• 6th kill - Killing dominating player is 520 G comparing to 647 (80%)

Normal reward growth is 20%. In Proving Grounds it growing from 5% to 10% - probably.
