Not sure why someone downvoted you, but this is actually a pretty good setup. There are a hundred ways to arrive at sharp, the journey there is far less important than the result.

Full disclosure, I have one of thse pull thrus and occasionally if I get a really abused western knife I'll save the guess work and use it to set a new edge.

If you are using a western knife like a Whusthof or Henkel, or any other german brand, even Cutco for the matter, the blade angle is going to be somewhere between 17 and 22 degrees. If your knife can support this angle (IE its not a calphlon or cuisinart) then this a great way to reset the edge before moving down the stones. If you can visibly see knicks on your edge use the pull thru you might have to run it a couple times until you feel it cutting the blade (depending on how dull your knife is) next move up the grits on the stones, using the 1000 to refine then the 6000 to polish. imagine flipping an almost microscoping burr back and forth (can see it if you look closely, you can definitely feel it), once you work one side and go to the other, dont bother going back, you are actually doing more harm than good because you risk snapping the burr off. Once you finish on 6000 you can then alternate sides to "cut" the bur off. Think of it like removing the tab to a soda can. Bonus points if you have an old belt lying around, cut it and glue it to a wood block. and you want to repeat this maneuvuer on leather. start with the knife almost flat and alternate bringing it just past the working angle. This will pot a mirror finish on the blade and you should be able to slice paper with ease. if you want to pony up.

If you dont feel like finding a peice of leather I use this one from amazon It even comes with some polishing compound!

Edit: I just checked that stone setup, throw away that angle guide. You don't want to over think that part, you can feel where the edge wants to go. I bought this electronic angle cube when I first started and it just got in my head. Ended up with worse results than just feeling out the edge. It would be great for a table saw for the day I can actually find a space big enough for woodworking so all is not lost.
