Si sono misurati più volte (almeno 10) sia il peso a penna carica, che a penna scaricata. Dalle varie misurazioni si è ottenuto il peso a penna carica e scarica calcolando media e deviazione standard. Non ha senso infatti utilizzare il valore più alto, il caricamento perfetto non esiste, quello che costituisce una indicazione di quanto nell'uso ordinario la penna carica davvero, è la media.

We measured several times (at least 10) both the weight when the pen is loaded and when the pen is unloaded. From the various measurements, the weight for a loaded and unloaded pen was obtained by calculating average and standard deviation. There is no point in using the highest value, the perfect filling does not exist, what is an indication of how much in ordinary use the pen actually charges, is the average.

The value when the pen is discharged used to estimate how much liquid remains in the [[feeder]], but we took as an indication of the filling capacity the value with the pen is fully filled, because pens are filled once the ink is finished and no longer reaches the nib, and this also includes the one present in the feeder. However, you can use the value with the pen empty for a fairer comparison with the capacity of the cartridges, as it indicates the capacity of the filling system alone (with cartridges the additional capacity of the ink held by the feeder when it is immersed to charge is not available).
