Answer: The 76% staking supply is a good starting point, but it's important to remember that the end result of following a -90% decline is still below 0.1. Depending on the size of the staking supply, this could result in a much smaller fraction than 0.1. For example, if the staking supply was 100, then a -90% decline would result in a final value of 0.01. Therefore, it is important to consider the size of the staking supply when calculating the final value after a -90% decline.
