--range is of course not immune to spoiled ballots, but it seems to do
better than
rank-order ballots (IRV, specifically) and (and this part is
surprising) plurality voting,
at reducing spoilage.

But range is not better than approval voting at reducing spoilage &
voter errors.

See   http://www.rangevoting.org/SPRates.html

although this page could use some updating (it refers to various new data,
which you can examine via hyperlink, but ought to be updated to incorporate that
data directly; if you edit this page's plaintext source to do that &
email result to me that'll happen)
