since January 2003, the "Software in the Public Interest" (SPI) project
uses my beatpath method. However, they use an extreme way to handle
truncated ballots.

In my opinion, this way to motivate the voters not to truncate their
ballots is too extreme. When there are many candidates then this way
to handle truncated ballots will make many voters use "donkey voting"
(aka "alphabetic voting" where the candidates are listed in an
alphabetic manner).
