The most common mistake is optimising for the first order instead of the fourth, which is where Diamond 4 economics actually settle.
Why maintenance schedule matters on the Diamond 4
Regular cleaning of contacts prevents most intermittent faults.
Seasonality interacts with maintenance schedule more than most forecasts allow for, so a rolling review beats an annual one.
