If a credible reference letter talks about two different achievements (in one letter only), can we use that as OC3.1 and OC3.2, they are two different achievements clearly mentioned, but just one letter.
If it’s one letter it is only one piece of evidence document. You can use it as a reference letter in OC3 and it can cover two different achievements but you can use it only once as a unique evidence for this criteria.
many thanks @pahuja . Is it ok to screenshot the relevant para from the same letter showing specific achievement in two different examples of OC3 (3.1 and 3.2 documents), while submitting the letter only once, or it will be considered as using the same letter (evidence) twice? Or is it better to just reference the letter as text vs. screenshot?
yes, two different commercial impacts are mentioned in one reference letter, as it is practically not possible to get two letters from same prominent personality.
My question is do you have two pieces of separate documents talking about these two stories with self claims and other backing evidences. And a third evidence document of this letter covering the two stories. In total 3 docs in OC3?
The question is can I use the separate screenshots from the third (evidence document) in the my two pieces of separate documents talking about these two stories.
Yes! You can use one reference letter for different evidence set in the same criterion because its focused at just one area. For instance: OC3 - Contributions to the field
Regardless of what you have in your OC3.1, OC3.2 and OC3.n they must point at contributions to the field, so a reference letter that talks about contribution to the field can suffice for this criterion. However, you won’t have the letter attached to OC3.1 and OC3.2, it will appear as if you are reusing, and will give a negative perception.
So, the letter can be added as an evidence under OC3 - Reference Letter (Contribution to the field), and it will validates what you have in OC3.1 and OC3.2.
