I am not familiar with YAC POS calculation. I see this line here
Each chunk of eligible coins has it's interest calculated based on the chunk's age in the range between 30 and 90 days.
Does it mean for POS generation if I have 100 YACs in the wallet for 1000 days I can only expect 100 * 90* 5% / 365 reward if a POS block is found? In PPC POS calculation the probability of finding a POS block is based on coin age capped by 90 days but the reward value itself is not capped. In the above example I would expect 100 * (1000 - 30) * 1% / 365 reward.
