From the dozens of pages I have read so far it seems that the 2+2 or the current version 2+4 may not be the way to go. See the following.

It also seems that for treating fuel Sta-Bill might fit better.
It also seems if you are looking to clean varnish etc out of your carbs, and wanting to reduce carbon that Sea Foam would be a good product to use a couple times a season heavy to de-carb etc. and at the end of the season to store your boat along with a good fogging oil.
And Sta-Bill in your fuel.
Or from what I am reading now with the E-10 it is best to store your boat with a empty tank.
