It contains notes showing the end result (10)
I believe the answer is:
scoresheet
'it contains notes showing' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'end result' is the wordplay.
I cannot really see how this works, but
'result' could be 'score' (I've seen this before) and 'score' is found in the answer.
The remaining letters 'sheet' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'the' is the link.
Can you help me to learn more?
(Other definitions for scoresheet that I've seen before include "goal to get on this?" , "Record of players' performances" .)
