I am trying to get a fare I found on ITA ticketed, but can't seem to get a knowledgable answer from travel agent or United 1K line. I specifically want the BK1YAU fare because it books into B - fully-refundable coach with 150% EQM bonus and near the top of the upgrade list. I've never missed an upgrade with it; although I strategically monitor loads and use the flexibility to avoid days it would have failed.

My trip is a combination of legitimate places I need to work, family I'd like to see, places I'd like to go, and airports in good locations to maximize the miles.
I know the fare has a four stopover limit, but unlimited transfers of sub-24 hours (I have many over-night layovers), and I don't touch the same airport twice in either direction.

It prices fine on ITA:

I know that the RTW and some award tickets specifically state a limit, but the fare rules for this fare say unlimited. Is this an unspoken rule? Should I trim the fat and/or break it up? Obviously breaking the fare will make it much more expensive.

For those that are wondering, if I can get it to ticket, it would be 40416 EQM in one trip. At 12.07 cents per EQM it won't interest pure MR types, but its a great price-point for it fitting my needs and the high probability I'll do the entire trip in business/first.
