How do you survey-match a job that is half product manager and half data analyst?

Our fintech in Singapore, about 400 people, has created a family of 'product analytics leads'. They own a product area's roadmap and also build the models and dashboards behind it. There are 14 of them and more coming.

Neither survey we take part in has a match I would put above 70%. Product manager benchmarks come out around 18% higher than senior analyst benchmarks at the same level, so the choice matters a great deal.

Do you blend, pick the dominant half, or do something else? And how do you document it so the next analyst understands what was done?
