I waited a full year of electricity bill payments to finally activate the estimate amount based on time of year. Electricity bills vary significantly seasonally and I was looking forward to improving my projected balances using this feature.
Unfortunately, it doesn't seem to work. Instead of using the corresponding previous year's monthly bills to estimate the values separately for each coming month, it simply used last year's January value for all coming bills. This messed up my projected balances. It's worse than having it manually set to an average fixed value.
Am I misunderstanding the feature or is this a bug?
