淵

Not counting the water radical, the rest is 8-strokes because the dictionary says it is. However, I naturally write this as 9-strokes and am wondering where I’m going wrong with this. I figure it must be one of the 90-degree angles that’s on the four corners of this character.

The top right and bottom left 90-degree angles I write using 1 stroke each.

The top left and bottom right 90-degree angles I write using 2 strokes each.

So where’s my erroneous extra stroke coming from? The top left or bottom right?
