I m reading a lot of different recommendations for the pitch slope of gutters on fascia anywhere from 1 8 per foot to 1 4 per 10 feet or to completely level. For example for every 10 feet of gutter they need to drop 1 2 inch from the high end to the downspout.

The minimal slope needed for proper gutter drainage is 1 25 cm 1 4 inch for every 3 metres 10 feet of gutter. For example if you have 30 feet of guttering the calculation is 1 4 x 3 0 75 i e. If the length of the gutter is 10 5 metres 35 feet the amount of slope required is 1 25 cm 1 4 inch multiplied by 1 metres 3 5 feet which when rounded up is 2 5 cm 1 inch. Calculate the gutter slope by dividing the length of the gutter needed by 10.
