Where do we put in feedback on specific content of freecode, so that we know that content of freecode has a > 90% effective/retention rate, and continuous cycle of being made better -- significantly -- every day?

where do we put in feedback on specific content of freecode,

and later get a message of when that part/section of the content has been made better,

so that we know that all parts of the content of freecode has a > 90% effective/retention rate,

and continuous cycle of being made better – significantly – every day?

and that things are actually being made better based on the retention/success rate of the content

and what content is actually more helpful than other content based on actual evidence

since we all care about making the content of freecode better

let me know

any easy way to edit the content so it has 1) much much better clarity and 2) much muc better UX to new ppl?

if it’s not measured are we just gonna guess and pray and say that taking an unknown medical drug is good for us? that wont be good for anyone or socetiy
