Didn't get a chance to look over all of this before I needed to leave the office.

I think its looking better, thanks for the updates. It looks like there's still a few opportunities to simplify.

I'll be away until after Easter. I expect the other reviewers will have similar comments to me, so I don't think I'm a blocker for progressing this.
