Distributing points among options (dynamic ranking)

Hi all!

To receive better quality insight from ranking questions, I want to ask respondents to distribute 10 or 20 points among options. 

I saw that other people were looking for similar solutions (100% total) and specific weights for ranks. However, apart from hoping that respondents will a) read the question fully), then b) do the maths properly and using a matrix structure I have’t seen or come up with any solutions. And I am a bit worried about essentially getting unusable data out of that option. Any other ideas?

And to all the Typeform product team - this is a must have for robust data collection practices! 

Thanks so much!
