Yep. It would be even better.
The initially mentioned 50% discount existed in our blueprints from the very beginning, and even STE Calculator has been using it from the first version introduced during STE presale. And the code is still the same and working fine with the new system. You may notice that 30% of the commissions go to the A2A-SHOP instead of becoming the exchange's income to be later distributed to the STE holders. Well, as shown above, it is not burned, and, as prices of the A2A rise, it will be sold out from the smart contract eventually. STeX will account for all sales from the A2A-SHOP as revenue, so that's clearly a delay in commission distribution and not a waste of 30% for the STE holders.

Now let's study two cases closely:
Let's assume we have an equity of 100 BTC of daily profits on STeX exchange in different coins.
With the old system, with 100m STE tokens in circulation, each STE token is entitled for receiving 1/100m from 100 BTC = 0.000001 BTC
With the new system, where we are burning about 30m STE at the end of the ICO, and issuing less founder's tokens, the total STE supply estimated to be around 50m or less. In this case daily share of each STE will be 1/50m from 100 BTC * 70% = 0.000002 BTC * 70 % = 0.0000014 BTC
In other words, with the new system you immediately get 40% more for each STE you hold, and not only that!
Additional 60% transferred to the A2A-SHOP will eventually be sold and distributed between STE token holders, raising difference in the outcome of the new and old system to 100%. It's doubling!
