I think you are doing ok. I know it's frustrating though.
If you have any fish flake you can add a tiny pinch, this will add some phosphorus to the water which can sometimes be a stall issue.
Is your pH over 7 still?
I'd just do 2ppm every 3-4 days instead of every day. With this you will no longer need to do any water changes.
Here is how it was explained to me... There are two sets of bacteria. Set A eats ammonia, poops nitrite. Set B eats nitrite, poops nitrate. Set A is well established. It's B you're waiting on. They are there or you wouldn't have the nitrates at all. Both sets have very slow reproduction rates -- even under ideal conditions, the doubling rate is about fifteen hours. That's extremely slow for bacteria and the reason that having a good population from seeded filter media makes cycling exponentially quicker. Set A will not perish if you ease up on feeding them. They are capable of surviving for weeks with no food at all so you don't damage them by skipping doses.
The thing with fishless cycling is that it does not replicate real life conditions. It would take a lot of fish to produce 2ppm ammonia per day. So, waiting for set B to be able to handle that allows full stocking from the day after your massive water change. If set B is present (which they are) and processing a good amount of nitrite, then the setup could handle fish. Maybe not stocked to the brim yet but most folks don't stock that way anyhow.
I started with a filter containing the bacteria that were handling an established 6 gallon tank. I moved it into a new canister attached to a 65 along with the three fish from the six. I've been adding fish a few at a time ever since and the filter keeps up. No ammonia, no nitrite. I'm sure you have enough bacteria to do this. Folks just hesitate to recommend it because waiting for the bacteria to handle 2ppm in 24 hours feels safer to them.
That's great news, congrats! Although sorry to hear there are other issues. There always is something isn't there (I mean that in general, not at you! lol)
Haha, I know what you mean

Above issue if you have any thoughts?
The silver dollars will probably eat the live plants in your tank.
The link you provided, although appropriately titled, oddly enough takes you to a 2002 thread about using the Berlin Method in a SW reef tank. Julian Sprung is mentioned in the article. The name rings a bell because back in the pre-internet days one way of getting info was through mail correspondence. I had written him a letter with questions about reverse flow UG filtration and redox potential and he was kind enough to write back.
very confused as the link above takes me to my thread I created? How strange!
Lets try again:

I checked it out, but no ideas from me sorry I know a lot about the science stuff, but not so much about diseases, except for a few.
Sounds like they are improving though?
