At this point, hostile ECM is at 37 dice, so we should be good there. A few more would be good, but we're in the mostly-safe zone. With Worm and Tranquil, we need 12 successes-before-bonuses to get >=30 successes-after-bonuses, so we've got about a 99.0% success chance on that - I'd always love a few more dice, but unless my math is wrong this should be good.
(For the record, I ran the same overall-success-chances-by-dice-and-required-successes script on Missiles Analysis, and it returned 99.99% success chance, which is quite heartening.)
Empty Veil is doing better than it was, with a new average of 23.5 successes (after bonuses and Empty Trees). Even if they're rolling 40 dice (twice their last-attack's ECCM), we should still be just barely favored to win this one.
Soothe is looking much more hefty... but still not enough to do much, probably. Still, we should definitely learn their defensive psy strength, and we might just deal some actual damage.
