I also wanted to send a brief overview of what I think the most likely scenario is based on the current evidence. I've followed this thing extremely closely over the last 4-5 days and wanted to share my thoughts based on all the current information before signing off for a few days.
I agree with a lot of the consensus that Justin may not have been Mike's #1 accomplice. He definitely could've still been involved in some way and at the very least, was extremely negligent in letting this go on under his watch. I would say there's a 50% chance he was on it as well, but I firmly believe Taylor Smith was Mike's #1 accomplice and perhaps, the only one.
Taylor commentated on 7 sessions in 2019. Mike only played in 2/7 games, one 1-3 and one PLO8, neither game very deep. There is no evidence of him superusing in these sessions.
As far as Mike not superusing when Justin is out of town except for 2 sessions, I believe the answer to this can be found by the location of the poker room posted yesterday by Veronica.
As she mentioned, sometime last year the curtain was placed in between the poker table and the desk/booth. She mentions Justin and the "gentleman running the stream" were the only ones back there during the stream. Assuming this mystery "gentleman" is Taylor, I think we can conclude he was the main accomplice. I couldn't find his specific job title and am not sure if he was in the "tech room" or in the desk with Justin, but am assuming this was him for all extensive purposes. I would like any additional information on the employees involved in producing the stream and who was located where and their job titles.
Whenever Justin was on vacation, I believe he had a replacement (other floor guy who worked under him) who spent time in the desk and thus prevented Taylor from streaming to Mike. Also, whenever they needed Taylor to fill in the commentary booth, no cheating occurred.
The last open question is the method the live information was sent to Mike. Based on the PLO hand I posted last night along with other evidence. I think Mike was watching the live stream on his phone. This explains him constantly looking in his lap. I also believe he was wearing a bluetooth under his hat, but this was not the primary source of his information. I believe this was primarily used for telling him how to play hands or communicate if any unusual circumstances came up. This can explain how the changing of the cards in the 89ss was executed. Both parties would have been on the exact same page for them to execute the timing of this. As far as how the stream was technically sent to Mike, probably some type of program installed on Stones' computer.
I don't think Mike or anyone else had access to turn/river cards through bracelets, keys, etc.
Last, I am somewhat skeptical that anything significant will happen legally to Mike and his accomplice(s). If the Casino's defense attorney who is currently performing the "independent" investigation does another cover-up investigation, when the civil claims are processed and any investigation from the relevant gambling authorities, I do not know if Mike's results will be enough to be found guilty. While everyone reading this knows that his results can be proven and are statistically impossible without cheating, I don't know if the same will hold true when looked at by a judge or jury. The reason is the defense can use evidence from all the sessions even the ones where he wasn't superusing. Based on my data, I think he was only superusing in something around 30/50 sessions in 2019. He still had a positive win rate in these sessions and I think it will be tough to distinguish in court which sessions he was superusing in. The defense may use examples where he played sub-optimally in these non cheating sessions. The investigators will need to find some type of trail, either through IT records or bank records, to have a slam dunk case. I'm sure I made a ton of errors in this last paragraph relating to the legal proceedings as I am not familiar with the process/not a lawyer, just wanted to point out a few of the reasons why I am skeptical.
