Still can't help feeling like your graph is a bit off regarding Kimi and Fernando so far this season. After Spain RAI seems to be closer to ALO than to VET, even though the actual gaps were 15 points and 4 points, respectively. Furthermore, RAI and ALO seem to almost equal after Monaco, even though they really had between them a gap bigger than what they had after the season opener (but the graph certainly does not convey that).
Thanks for pointing this out quaint. I double checked the data in Excel and I had marked only 15 points for RAI from China and Bahrain. Now it's corrected with 18 points for both races:
