I got $10 last week with no deposit and wager about $500. Since we are on the same VIP level, I start to think that $10 can be the base bonus amount for Platinum 3 and your $7 is additional amount from your loss. Maybe the minimum wager per week to get the base amount is within $500-$1000. Of course, it is just another speculation because we never know the formula of the bonus in Stake 
With VIP Level Platinum 1 my weekly bonus is around $12 without deposit but I receive tips every week from campaign payments and my statistics profit + my wager is less than $1000 so can we assume that $10 is the base bonus for Platinum I - III account? and $2 is additional over my statistics + wager. In general, Platinum I - III and Platinum IV - VI differ based on VIP benefits, we can see this on the VIP page. Things like this are always in question but we can compare it based on the information from each account, maybe those who are in Platinum IV - VI need to say something here regarding the weekly bonus so we get a more accurate comparison.
Bitinity is right, my platinum-I membership sets a base amount of something like 10 dollars or less. And I notice per 1k dollar wager, they back me 1 dollar as an honor. Sometimes, higher house edge games boost this payout rate more, I guess. So the bonus payout may vary depending on your VIP tier+house edge+wager volume. So it is very simple, some weeks you may get 5 and another 16, totally based on how much you played and which game you select.
