the worst case scenario for a trinket flip is a X:20 minute fight, which means you'll lose 1 trinket proc. if X is 3, you'll lose 1/4 of your trinket procs. if X is 2, you lose 1/3. if X is 5, you lose 1/5. however, your first trinket proc will be 30% stronger from BL, and another 40% from pool. that's 82% stronger, since they're multiplicative. if your other procs align with pools, they get also a 40% buff, if not, they're base. so your worst case, you have .82+X, where X is the minutes of your kill. for 3 minutes and 3 procs, that's 3.82/3 (because you need average for 3), is 1.27% avergage trinket value (which is worth another 27% uptime), or less than the trinket you lost.
if you do get lucky and your other trinekt procs also align with pool, that's 1.82+((X-1)*1.40) = 4.62, or 1.54 average.
This is just my napkin math about it. I probably made a mistake in here somewhere. If I did, feel free to point it out.
