Lol!
He showed his readings taken on 18 April and 19 April, and both were taken after meals. Where are the readings TAKEN TWO HOURS before meals? Never take or don't want to show?
How do we know he did not take those reading he showed us only 45 minutes after meals? Lol!
For all we know, if he took them 2 hours after meal, the reading could be 6.7.
So without his showing us his reading two hours before meals, the after meal readings he showed us are only his word, that it was 12 hours after meals!
