This is a classic response to a software feature request. “I don’t feel like I need it, therefore you shouldn’t need it either”.
It happens to every feature request known to man, discussed in a public forum.
Right now that is what you are doing: you are trying to convince me that I don’t need or want the thing that I have said that I would like.
I’m sorry, you are wrong: I would like what I have said I would like
I would like the graph to show me more emphasis on the vertical scale, and my reasons for wanting it are as valid as your arguments why I should not want it.
Note that the new graph also suffers from projecting improvement across time instead of games, so it penalises even further the performance of slower playing players.
Your current argument is that “nothing much in general happens to our ranks for ages - the climb from 25k to 7d is a long slow one - so there’s no point in making the changes as they go visible because they are insignificant, so let’s represent them as such”.
It’s an odd opinion from where I’m sitting, and I think the argument that “the journey is long so it is nice to celebrate achievements along the way” is equally valid.
Ironically, the old graph supported both use-cases - it had a zoomable vertical scale. Maybe that is what this graph needs…
