Been using reversed wedges on most of the vases that I have been doing, usually with small central angle on wedge. Made a new wedge to cut 9 sided object(ring). All my wedges are right angle triangles so the other angle on this wedge was 50 degrees. Here is what I found using it.
Make seven wedges cut at 50 degrees, 10 degrees short, add 10. No reverse.

Add a second 50 degree wedge (8 total). You now have 390. So take away 40 by adding reversed two 15 degree wedges and one 10 degree.

Add two more 50 degree wedges, making total of 10 and a 500 degree ring. Need to reduces by 140. Found two solutions. 10 -15 degree wedges reversed and one 10 degree inserted normally.
