Hey! I love the idea of tier-based allocations, but you need to re-calculate allocation's size for the participants. As example let's take a look into FreshCut project:
▫️Tier 30,000+ Pols Power: $500
▫️Tier 10,000+ Pols Power: $300
▫️Tier 3000+ Pols Power: $200
▫️Tier 1000+ Pols Power: $125
▫️Tier 250+ Pols Power: $50
From lowest tier for 250$ you need to pay 750$ to increase your allocation for 150%.
Same time from 1000POLS you need to pay more than 2000$ to increase allocation for ~80%!
And then you need to get extra 7000POLS for around 10k$ to get extra 50%, what's already really huge amount for such a small boost. I believe there should be something like mid-tier for 6500POLS, or 150% higher allocation for 10K POLS then 3kPOLS. And finally 30K POLS, 20K tokens different from previous tier, or 26.000$ it current price. For this again you get 60% higher allocation, but for almost 30k$.
I understand that this is super fresh feature for you, but consider recalculation please!
Might be usefull to increase allocations in that example for 30K, 10K and 3K.
