Eg. If 3 vote per block, I cast 3000 vote during some time, 1000 for myself, 1000 for backpacker, 1000 for cybnate.
If only one vote per block, during the same time, cast 1000 votes totally, 333 for myself, 333 for backpacker, 333 for cybnate.
The reputed ratio is same. “3votes per block” makes statistical data more smooth, and ocupies more blockchain size, that’s all.
