No way.... 850 SP means $0.14 if you are voting at 100% with 100% VP.... You may only have 10 vote a day using your 100% if you vote exactly every 2:54 hours... which means $1.4 a day for 10 votes in yourself... which would mean: $9.8 in a week. However, you must remember that you only get 75% and the remaining 25% goes to curation rewards... This means you have a $7.35 waranteed for 1 week... And you might possibly get the $9.8 for curation rewards on your own pots if only you are voting on them (not even bots, randonwhale, minnowsupport or the like).... You might get something more if...

But the idea is that you build followers and you feel great about being able to help people by voting for them, and supporting their projects. And alledgelly you might win more if you are good at curating rewards.

Well... this is why this gift DOUBLING the value on the 4-week investiment is a great way to recover at least your investmnet by voting for yourself on 4 posts/coments a day... and you can use your other 6 comments for other people and/or curating.
