I replaced my garbage disposal with a new unit and attached it to the existing drain with the manufacture provided straight outflow pipe. The new disposal sits a little lower than the old unit, which also had a straight outflow pipe. The result is that the outflow pipe is now angled about 5º down towards the disposal.

I'm guessing that's a bad thing as the ground up food sludge will pool towards the disposal end. What slope angle should I shoot for?

_{The level was just a touch too long to hold flat against the pipe, so that's why there's a gap. But you can see that the horizontal air bubble is just off to the T end.}

The T connection on the left is a split 1.5" baffle. The connection on the garbage disposal itself is full rubber with a metal ring clamp, so it can flex to a wide angle if needed.

Is there a combination level + protractor + measure tool that could tell me how much I need to lower the T connection by? How would I go about dropping the T connection by such a small amount? I was imagining disconnecting the pipe and carrying it into a hardware store...
