The weight cut percent is a percentage configured in each ruleset that determines by how much the subsequent ruleset's weight should decrease compared to the current ruleset for which the weight cut percent is set.
The weight cut percent is only applied if a new weight isn't explicitly set in an upcoming ruleset.
The weight cut percent can be used to automatically decrease token issuance over time. Rulesets with higher weightCutPercents and/or shorter durations will have token issuance decrease faster than those with smaller weightCutPercents and/or longer durations.
