David Kimura PRO said about 3 years ago on Gathering Questionnaire Responses :
Just some thoughts on weights... For the weights, I would recommend not trying to match 100%. It's not too difficult, but it's really annoying. So much front end validation to do and requiring the user to do some math to match up values to 100%. Instead, if you have 10 questions and you give them a weight of 50 each, then each question would be 10% of the total score. This will be much easier logic to handle. You could use a stimulus controller to add up each of the weight inputs and show a percentage value as you setup the questionnaire.
