But yeah... i actually anticipate a thargsday tick change... a realtime change across all instances would be a first.
The visual heart count indicator on the Titan does appear to be doing that already. And of course, what's a Fleet Carrier jump but a realtime change across all instances?
There may be more subtle technical reasons why it can't be done (so I'm not going to be too disappointed if they can't) but on the broad conceptual scale I don't think it would involve anything unprecedented.
Leigong would seem logical if Ctrl systems are significant.
That certainly makes most sense, I think - it's also low on Controls, it's going to go up from 14 to 20 at the end of the week so hitting it now should be a lot more efficient (and if it turns out that even 14 is too hard, there's time to switch to stopping it getting to 20!), it's in a sparse part of space with few inhabited systems so if it does need trimming it's the easiest target and much easier to contain and starve of Alerts, and it'd probably get us the best data on what the difficulty curve looks like if everyone could be persuaded to move.
Progress at Taranis on Thursday seems to have been about half as fast as progress on Wednesday. That's (noting that the number of actual attacks can't easily be measured!) compatible with a few theories ... the two most obvious ones unfortunately giving extremely different results.
1) Resistance is proportional to 2**Keyword (so High is twice Moderate, and Maximum is four times High). In that case a Maximum strength Titan should fall in about 3 weeks of sustained attacks.
2) Resistance is proportional to 2**CtrlCount (so 7 is twice 6, and 50 is 8 trillion times harder).
I suspect the actual answer must be somewhere between those points - the other Titans are moving measurably on the Journal, and Raijin (which is huge) is not moving much slower than Leigong so the difference between 14 and 127 can't be that critical ... but equally, if Maximum is merely eight times harder than Moderate/High the current distribution of progress still implies that >>99% of firepower is being focused on Taranis, which is implausibly high.
