Ortho Killex Concentrate + Ortho Dial n Spray

Hi guys,

I've got tons of dandelion this year and it's impractical spot spraying 2900sqft, so I decided to try the Ortho Killex concentrate with the Ortho Dial n Spray I have.

My question is, on the label it says to use setting 6 on the ortho dial n spray and for backpack sprayers, to mix 6ml/L which will cover 50sqft. The Ortho dial n spray states that it puts out 2gallons or 7L of water per minute (from memory), so theoretically, I should have covered 300sqft in one minute and have used 42ml of concentrate? Is that right?

Really just wondering if I am using the product properly... thanks.
