It is best to not repeat the same documentary evidence in multiple criteria. The guide clearly states not to do this.
The typical approach is to have 3 documentary evidence for each criteria and then you have one more evidence for one of the 3 criteria (i.e 4 for one criteria ) .
So it will be something like this:
MC1
evidence 1
evidence 2
evidence 3
OC1 - innovation
evidence 4
evidence 5
evidence 6
OC2 - recognition
evidence 7
evidence 8
evidence 9
evidence 10*
*10th evidence could have gone to any of the 3 criteria depending on your story.
Now you should also be strategic in your application , and selection of evidence.
Should you not get endorsed, when it comes to endorsement review (appeal) , you are able to mention that evidence x which you submitted for criteria Y could also count for a second criteria.
What is important to note is that the assessor is looking at your entire application. The assessors sometimes will make this summation themselves. They are humans.
