I like it how this motion creates a rule set of what do to based on defined thresholds.
Let me see if I understand this right
Thereās a limitation of money that is used for NSR buybacks for tier 4 funds below $150,000 to $7,000/week, but if tier 4 is above $150,000 10% of the excess are available for NSR buybacks?
That would mean with tier 4 at $160,000 only 10% of $10,000 would be used for NSR buyback, right?
Donāt get me wrong - I think dividends in addition to NSR buybacks is the way to go.
What I find problematic is that all buy side liquidity in excess of $150,000 shall be used for PPC dividends.
What if selling 100,000 NBT piles up to the current tier 4 buy side funds?
As PPC leave the Nu ecosystem this creates danger for the peg stability
If the majority of revenue were being distributed as dividend, the rational choice for NSR holders (if things really go pear-shaped) is selling NSR instead of bailing out Nu.
Selling NSR makes protecting the peg by selling granted NSR even harder.
My take is that Nu can only afford a fraction of the revenue being paid as dividends.
Iād rather have 7b4955e91781e0e32f1e0c0c974fd4a7a9f972a3 untouched, lower the threshold at which PPC distributions kick in (to to something between the $150,000 from this draft and the $80,000 from 7b4955e91781e0e32f1e0c0c974fd4a7a9f972a3), but create a ratio that is used for PPC dividends.
Something like
This way thereās a buffer between $80,000 and $120,000 in which only NSR buybacks are conducted.
If the tier 4 funds are below $80,000 nothing happens in terms of distribution.
If the tier 4 funds are above $80,000 and below $120,000, liquidity in excess is being used exclusively for NSR buybacks.
If the tier 4 funds are above $120,000, liquidity in excess is being used evenly for NSR buybacks and for PPC dividend distribution.
If the tier 4 funds exceed $120,000 Nu is in such a good shape that it can afford paying dividends in addition to conducting NSR buybacks 
Example:
Tier 4 funds are at $200,000 for whatever reason (NBT sale, rising BTC ratesā¦).
$80,000 are excluded from calculation of NSR buyback and
$120,000 are excluded from calculation of PPC dividend.
Thatās $120,00 in excess regarding the NSR buyback motion. 10% of it or $10,000 are being used for NSR buybacks.
And thatās $80,00 in excess regarding the PPC dividend motion. 10% of it or $8,000 are being used for PPC dividends.
Does that make sense? Having a buffer before PPC dividends kick in?
Remark: current tier 4 buy side is at 443.9 BTC (466.2 BTC - 22.3 BTC). At current rate of $445 thatās $197,535.5
If NSR buybacks and PPC dividends were based on this amount, it would be close to my example above 
Iād very much like to have variable values for the thresholds (in relation to the total NBT in the wild) instead of fixed amounts like $80,000 and $120,000.
If Nu needs to sell NBT soon, because of rising demand for NBT, the buy side buffer should be increased accordingly.
I canāt imagine the peg being safe with an untouched amount of buy side buffer in a future in which double, triple or even more the NBT is out compared to now.
But that might be something for a different topic.
