the problem is that these are NOT to be compared to voobly or hd ratings. on the contrary i would make it even more different and do #1 as zero elo and everyone else going lower from there. elo lists with different datasets shouldnt give the false impression of comparability / similarity. a static elo list like this is only meant to show strength difference between players, not comparability with different datasets. if u want that than elo is just the wrong measurement formula to begin with.
