You say ...100??

• 20 chocolate bars each rated out of 5 = 100
• 100/8 = 12.5   So, 12 chocolate bars with 8 nutritional factors = 96
• 10 nutritional factors x 10 chocolate bars = 100
• 20 chocolate bars with each nutritional factor rated out of 5 = 100 

I am going to work with the concept of the latter to make up my collection 100.
