Voting like this in SV: A B C D E with that context, for me it doesn’t make sense,
For me the threshold is proportional, in fact 20 and 100 $ are so low compared to 1000 $ that with a range from [0,5] I would not vote for them, and if I vote them more granularly, the fact remains that I give him very few points (almost useless).
Using range [0,100], however, I don’t understand your vote. I would vote about this: A B C D E
By observing your vote, are you aware that giving 3 out of 100 points to candidate B is practically useless?
In general, all of this seems very (too) ambiguous to me. Our ways of reasoning with range [0,100] are both sensible in their own way but they are also very different, yet we have the same interests (theoretically).
From this point of view, the ranking is extremely better (it would not have any of these ambiguities).
The point is that, if there is an ambiguity problem, to say that it is the fault of the voters who (in your opinion) vote in a non-intelligent way, does not solve the problem (which, however, is resolved by other types of votes, such as the rankings).
Anyone who designs a voting system must think about these things.
