Hi Lau,
I don’t have access to the raw survey results, but here are some screenshots from the post-round badgeholder retros.
Regarding the expert vs non-expert allocations, I have in my notes from the RF5 retro that ~80% of survey respondents preferred the expert allocations from RF5.
This thread also has a lot of feedback on RF3, including issues with lists and the relatively low allocation to onchain projects. Trent from Protocol Guild also had a good essay about the perverse incentive to “atomize” work in RF5.
Were there other sources you had in mind?
