Thank you sir

Sir Why we take 5 average TD readings

[@civiltechforall2474]

If we want gap b/w 20-25 then we can fix any value between 20-25 say we can keep 21 or 22 or 23 or 24.
How ever some people take average of 20&25 which is equal to 22.5 which was in between the range.So we can follow any of them.
