I have tested this quite thoroughly and noticed something:
Only add validator 2812 and check the very first day of the diagram (01.12.2020):
Both app and explorer report 32.01922 ETH (explorer has additional digits but this can be ignored) yet the converted value in € differs: The app reports 38,920.33€ while the explorer reports 39,092.91€ (the cut off digits don't accumulate to ~100€ difference).

Can this be ignored or should we investigate?
