I’ve crunched the numbers again this morning - and it has taken 8 ads viewed to accumulate .1 This equates to 0.0125 BAT per ad (as opposed to the previous 0.05 per ad). This is a significant decrease.
Upon scanning other related threads, i can only see one Mod response thus far from @eljuno in https://community.brave.com/t/decreased-amount-of-rewards-per-ad/129247: “Nothing changed. Because it’s vary for each ad. And it’s always 70% of the revenue share.”
Since yesterday’s upgrade to v1.9.76 Chromium: 81.0.4044.138 (32-bit), i’ve personally been receiving the same ads as i did prior to the upgrade (ie. BlockFi). It seems a stretch that the payment structure would have changed for such ads in the last x2 days and coincidental that it has occurred at the same time as an upgrade.
