Range voting is a voting method for single-seat elections and
therefore is not suitable for SPI board of directors election.

We elect 3 or more directors in each election.

All A, B and C will be elected as board of directors in SPI case however.

We wouldn't even run the election, as they would be elected unopposed.

Do you understand at all, how SPI board of directors elections run?

It does not work for multi-winner elections... I think this needs
repeating again.

It's the best system to elect proportional representation into the
multi-winner elections.

It sucks a lot for single-winner, luckily we are multi-winner.

We are picking the appropriate method for the appropriate elections,
and we are not using single-winner elections to justify choices for
multi-winner elections.
