I like your version (the drawing) better than one in the photo. Your drawing has a sweep gate--their's does not that I can see. Some of mine don't like to make a right angle turn. The good thing about those panels is you can shape it like you want it as you try different versions. The bad thing about those panels is it only takes one asshole cow to turn it into new geometric shapes never before seen by man. Once you get it like you need it, put some posts down in the pressure areas to hold the shape.
I have way more trouble in the 12'x24' sweep alley (sweep gate is halfway down the alley) than anywhere else.
I do my sorting just after where the sweep gate closes. Sliding gate, then a 3 way sort gate. Right leads to loading chute. Straight leads to headgate. Left leads back out to another holding area.
Your drawing is a starting point, apt to be changed and improved as you use it. You'll get it like you want it eventually. One antsy animal is all it will take to show you the weak areas. :lol2: :lol2:
