Here's a different way of putting it.
T-Compustick probably did more work that the average person running BOINC on their computer in the background will do, and it was maybe going to hit 1K. My daily computer which is running BBP and BOINC and is pretty decent for its age (Xeon X5650, 24GB RAM) has been up since Feb 8 and is peaking at about 1200 RAC. It's probably representative of a "normal" user which I define as anyone running only one PC. Right now that 1200 RAC would give it a Mag of 1200/700,000 of 1.7. I firmly believe the Team RAC will exceed 1M within 10 days if not substantially sooner. So on the very limited horizon that PC would end up with a Mag of right around 1. If the reward structure is adjusted to 20-36-36-8 as has been said it likely will, and the "full block" right now should be worth about 18,500 BBP. If the block timing gets to 205/day, then the daily PoDC reward would be 205*18,500*.36 = 1,365,300. So the above "normal user" would receive "roughly" 1500 BBP / day in the very short term. I don't see the need to retain/purchase 5K-20K coin to receive that reward as a high burden. Or put another way, I think the harm they incur is substantially less than the benefits the coin receives by requiring the flexible staking.
Finally, most regular computers are going to grab far far less. The number 100 team is the California States Universities (CSU) Team. They have 10 active members, and only the founder has more than 275 RAC. That is a typical computer user. People with thousands of RAC are not in my mind typical. But in the end, this is driven by the idea that me, as a vocal supporter of the coin and having 30K RAC should legitimately be expected to hold more coin to show the same level of commitment as someone with 3K RAC or 300 RAC. For the coin, the benefits are increased price stability (coins held are not likely to be quickly sold if the price moves moderately), increased resistance to botnets and in my mind...a more equitable proposition (of whom much is given, much is required).
I think staking is a good idea. I still would like a way for people with low hashrates to be able to mine, but I haven't though of a good way to do that yet.
So here is the thing, and it's just me for now. I have a magnitude of 160 and 20k BBP/mag is currently winning, that means I need 3.2M BBP, don't you think that's a bit much? What if we did a log curve? At 20K/mag, we are asking 20M BBP total to be staked, current supply is 452M BBP, which is 5% of the total, if that is the case, the staking is not really making a dent, then do we need to do this? I feel like the real goal here is that you are trying to even out the rewards among lower powered researchers. In the spirit of BOINC, they don't even do that.
