Hi This is very basic question , To understand the  When Rule best practices , 

Note: I am using below mention When rule in CDH project where to check eligibility crietria which means this when rule can be executed against few million cutomers data hence trying to understand a best practice .

Example of when condition .

business  Requriement :  

Users are eligible if balance amount is greater than 0 but less than 2000000 

and maturity date is in next 15 days. 

Option 1 to create when rule : 

A - balance amount > 0 

B - balance amount < 2000000 

C maturity date > current date

D maturity date < current date + 15 

Logic : ( A AND B AND C AND D )

Option 2  for when rule :

A - (balance amount > 0  && balance amount < 2000000 )

B - ( maturity date > current date && maturity date < current date + 15 )

Logic : ( A AND B )

Please suggest which is the best option for performance . certainly Option 1 is good for Business user as its more readable but at the same time I am trying to understand is there any considerable performance improvement if I go with Option2. 

Or please suggest any better option whcih can improve perfromance considerably .

Thanks in advacne.
