Thank you very much for the recommendation!

Allow me to make a couple of remarks:

If one curator votes 40 times a day and the proxy contains 10 curators, there are 400 votes a day.

Exactly on point: according to the curation data from the previous seven days, upvotes from empo.voter have been distributed through +450 posts and +10 comments.

in short it's a tokenized curation trail with a soft pegged to HIVE token that earns a HIVE yield for holders

Although it's on the roadmap, it's not yet clear when the HIVE rewards for holding PWR will start. IMHO no one should be participating now on PWR for the sole promise of HIVE rewards (should be done for the generous delegation APR instead)

I have even considered the possibility of supercharging the APR of the pool (as long as the HIVE backing allows it) instead of paying dividends.

But this is something that will be considered as time goes on, there are many unknown variables as yet.

The model is very sustainable and gets better with time and there's no real risk as you are only required to delegate HP and not part with hard-earned liquid HIVE

That's the best part I've thought of. The worst-case scenario for Hive delegators is the opportunity cost in case they don't like the project and want to pull out their HIVE (and even with that they will probably make a quick profit through a competitive Hive delegation).

Regarding your strategy with SPI and EDS, you're covering all the angles so you should be more than fine. The best 'safe' strategy should be selling 50% of PWR rewards and pairing the other half with the HIVE you just got (since I expect PWR to slowly drop within the first few months as 'predatory delegators' come and go within the first month and maybe the next 5).

All in all, everything is almost ready, see you on launch day! :)
