5. the biggest problem is that the gutter debris goes everywhere i.e. all down the side of the house so you end up washing the sides of the house down. one house took us 3 hours to do that was 3 men.
You did not angle it right, other wise you would not have had that happen. I cant see why it took you 3 hrs either, this is a 5min job once setup so easy. You do get some come over i must admit, but this was all in my How Too.
Change your angle and you will not have it come over the side like you said. As i had this untill i sorted out a proper angle to do this 40 degree approx will be sweet.

Ps Pratice a few times and your get the angle right and you will be impressed with the results and the time saved.
