I LOVE a game of speculation.
I don't think she was running out the clock on purpose. As some other MNs pointed out earlier, the more she dug into the SSD, or SHOOM, the more work she did in favouring the Rs through CA's clear and logical responses. She couldn't help but see that but having gone down this route she couldn't finish with zip, nor could she stop without having gone through all the ones her client wanted her to go through, so she kept on going in the hope that exhaustion would lead CA to say something intemperate or GCish to a degree that would undermine her credibility. She passed all those tests with flying colours.
And she was most definitely floundering about in the weeds of the SSD/ SHOOM and had to know she was doing herself no professional favours by continuing EXCEPT that it became increasingly clear to us all, I think, that this was not a mess she was making. She was following the instructions of her client.
And so I think you might be onto something re the lack of planning around the SSD/ SHOOM but I would speculate a little further.
As we know from the outset, HH was all befuddled because she was only recently appointed. I suspect she didn't really have the time or the desire to wrangle the SHOOM but I also suspect ST thought the numerical imbalance told the whole story without having any need to go to the SHOOM.
However, I think it became clear to ST whilst being cross-examined that no one was buying the numerical imbalance as proof of anything (as has now been proved it was, in fact, only proof that MANY TRAs were being aresholes on Yammer) and, clocking that, he then immediately instructed HH to introduce it. (She has said a couple of times that she wasn't expecting to rely on it so heavily – eg when she would delay the court by getting lost – so this would make sense. I'm sure if we went back to TTs of ST's testimony we might note breaks where ST could have given such instruction.)
Because he has been soooo used to the TRAs being OUTRAGED by the posts from SEEN and so OUTRAGED that their posts have been moderated that he genuinely believes this is a tactic that will succeed.
I think there were times the J has shown himself willing to consider a couple of things raised as evidence of imbalance, but I also think that it is reasonable for him to do that in order to demonstrate his reasoning through a close examination of the detail. I suspect what has happened in addition to those tiny elements that might, to a judge inclined to do be anal about process and not at all forgiving of process in the paradigm of chaos produced by TRAs, support the claim are the emerging points CA managed to introduce about how GC are misunderstood. It is only that misunderstanding that justifys the C's claims at any level and if you are to look fairly at both sides you would have to take that into account. I suspect it is the first time J has heard that.
Which is frustrating as it is so core and yet he so often is ready to dismiss 'philopsophical' aspects. Yet is the continued, purposeful and ever-amplified 'misunderstanding' not the Sisyphean heart of the whole?
