Generating random array with conditions

Hi guys,

Perhaps a peculiar task. My goal is to generate a dynamic array with random percentage weights. Couple of rules on that.

1. Generate 30 weights.
2. Each weight must be less than 10%
3. Sum of all weights must be 100%
4. For weights that are above 5%, sum of them must be not greater than 40%.

My thoughts were I could use random array function with max in there, but I don't know how to incorporate sum up to 100, and the 4th rule..

Example List attached. Any help will be greatly appreciated!!

Thank you!

Solved it. =LAMBDA(x,LET(y,x,IF(SUM(IF(y>5%,y,0))<40%,y,custy(crit13))))(crit13)

Custy = =LAMBDA(x,LET(y,x,IF(SUM(IF(y>5%,y,0))<40%,y,custy(crit13))))
Crit13 = =LET(x,RANDARRAY(30,,,10%,0),x/SUM(x))

Interesting! Where can I learn more about "--c", haven't seen this syntax before? Thank you!
