That’s the way I would think about it.
Essentially I would work back from the trades you want to do/expect to do before price changes in R3, and if there are 3, do 1 this round.
So long as the sequencing of the cash works (eg you may need to downgrade in order to upgrade, so the downgrade has to be first/at the same time), and any DPP switching works, I usually just do the trade I’m most confident on, to reduce the risk of regretting it when you have more info.
That might even be something like Danger to Jordon, even if you don’t need a downgrade per se - if you’re most sure about Danger amongst your outs, and the Jordon amongst your ins, you could consider pairing those legs up even if it isn’t a trade you would consider in isolation.
Another option - probably not preferred, but viable if the extra info is worth more than the expected price changes - is to do two in R3 and save one for R4. Again, you’d need to check that the sequencing works, and the risk is that you have 2 other trades you want to do in R4, but it is an option. It’s probably one I’d consider if I was, say, trading out Gawn/Grundy but felt somewhat marginal about it, and thought a week or extra info would help maximize my chances of getting the decision right.
