85% - 88% is fine, providing the signal levels, on other satellites are correct.
My dish needs tweaking, as I haven't done it for a few years, but I'll wait for a good summer.
When setting up your dish, as you're using a 36v motor, it's important to get your correct Longitude, as this is your True South, your Longitude should be a little over -2, negative Longitude readings = West, therefore you should set everything to 0, dish/motor/LNB, the use your receiver, or V-Box II, to nudge your dish about 1.4 degrees East, befor aligning on 0.8W, so that 0, on your motor, then points at your Longitude position.
But as your so close, to 0.8W, this is just to tweak your setup, to maximise the signal.
You can use Dishpointer, to get an accurate reading, enter your Postcode, select 0.8W, from the drop down satellite box, then zoom in on the map, moving the green icon, until you have located your house, and where you have the dish installed.
You have a good satellite dish, and a good receiver, which you can make a lot more use of, especially if you have a HDD installed, and mounted, to record programs, and make the most of Kodi.
