Great Joern, thank you.
I have a suggestion:
It may be interesting to users to report loss of rating points due to
move and cube errors separately also, something like (perhaps would be
cleaner to get rid of the () lines too as in the suggestion below?)
OVERALL
Luck based rating diff. 100
Error based rating 1234 1321
Chequer errors rating loss 616 629
Cube errors rating loss 200 100
One could also argue to put the last 2 lines under the CHEQUER PLAY and
CUBE DECISIONS tab but IMO anyone interested in the rating estimate will
always also be interested in the breakdown so it forces 2 clicks on the
user.
Best of all would be of course to have a 5th "SUMMARY" tab which can be
populated as desired by the user.
