I thought the point of a PID on a small boiler was to get the right temperature rather than trying to sustain the temperature through multiple shots
i.e it's better than a thermostat
Especially when your typical Silvia can have a temperature swing of over 30 degrees C!
The PID on my old Silvia helped the boiler stabilise but the temperature varied hugely when actually pulling a shot.
