Tom,
Never worry about causing me more work, I truly don't mind and enjoy the process. 
I understand your suggestion and we've tried that on a different layout where it didn't work out. Here though, I don't want to change Bob's design too much until he chimes in. You did give me a slightly different idea to get more space. I'm not sure why one reversing loop is larger than the other, so I simply made the upper loop smaller and moved it further to the right. I didn't change the baseboard yet, but you can see how much space it frees up.
I can also get more space by expanding the blue and green ovals, but that might result in too much of the blue line being covered. I'm waiting on Bob to comment on that.
