Hence the problem, we know they had issues in the simulator, no one crashed the a/c but they found different ways to safely land, we know the regulators opinions of those sessions.
We heard they updated manuals and procedures, no confirmation that all and sundry were happy with the updates, including the FAA.
Its not Boeing going to find new ways to screw things up, in my opinion, they are being set up to fail as the long list that the FAA and others can hold over the head of the MAX still exist.
As for the regulators allowing the MAX to RTS and fix outstanding issues later, my opinion again, since no one is taking new a/c now and Boeing has over 400+ a/c sitting down to modify before they can be delivered, nothing is going to change in the near future, at least nothing to positively affect Boeing's cash flow.
The a/c already delivered have to be modified, in itself that will probably be a few months, whether the airlines outside of the USA will use them is another story, as a lot of them are still closed to pax aviation traffic.
I guess I am being pessimistic but I get the feeling that too much emphasis is being placed on the test flights, my bigger fear is that once RTS is granted with a wish list of things to fix, at any given time, one of the regulators can go off and just ground the a/c again and restart the pissing match.
The sequence being followed is the same one as was posted 19 Dec 2019 to Twitter:

The "issues in the simulator, no one crashed the a/c but they found different ways to safely land" box is the first gray box, "Workload Evaluation", and it happened a bit after 19 Dec. It was always going to be an evaluation and not a test so did not block future events.
Tomorrow will be the next gray box, "certification flights". This could not happen till regulators felt all blocking items were resolved.
Then if/when the these flight tests happen successfully, then they go on to the JOEB "updated manuals and procedures, no confirmation that all and sundry were happy with the updates" resolution meeting. At that point they'll have all the info on the fixes, will have the feedback from the earlier evaluation session(s), have Boeing's latest and greatest training content, and "finalize training requirements" as the box says.
Again, the JOEB meeting could not happen till the set of fixes were frozen and had made it through testing, but the evaluation already happened and Boeing has sent around at least one set of training proposals, which of course now contains sim time.
Then once the JOEB "sets training requirements" the rest of the blocks are standard for any RTS activity.
I'm not too sure if too much emphasis is being put on the tests. The regulators didn't want to have them till all the non-training items had a resolution, either pre or post RTS. A whole sequence of glitches came up each step of the way. It *seems* at least FAA and EASA are on board with this being the set of things needed for RTS, and presumably some of the other regulators are on board as well. But yes, your fears could be true. It's pretty easy to project how one or more regulators will find one or more things they won't like and then we'll be back to the "need to perform certification test" phase all over again.
