Let's say there are 5 candidates and a voter bullet votes for their favourite. According to the m-rule (the "good" way), the points would be 1, 0, 0, 0, 0. According to the n-rule (the "bad" way) it would be 4, 0, 0, 0, 0 (or equivalently 5, 1, 1, 1, 1).

But 1, 0, 0, 0, 0 would also be equivalent to 5, 4, 4, 4, 4, which doesn't really seem that good either and is biased against voters choosing not to rank all candidates (rather than being unbiased as claimed by the article).

I've always thought the most logical way is to average the ranks. So if 5 ranked candidates would get 5, 4, 3, 2, 1, then bullet voting should give 5, 2.5, 2.5, 2.5, 2.5.
