I have a similar setup of dry-loop and just posted for the second time on Verizon Direct forum. Getting a little bit upset but starting to believe the posts saying Verizon wants to push out DSL subscribers. I'm in rural California so the only other game in town would be cable or Hughesnet sat. Had a good 6 months of solid 1mb down and .34mb up in May then starting in Nov it just went to pot. Settings before and after below.

Sometimes it does bounce back up to 864kbs down / 160kbs up but NEVER stays that way for very long.
