No prob. He’s someone you can learn a lot from too. (:
9S not supposed to have mealbreak. Try getting 9S to depart
JEI at 1010 instead so 3A can eat.
81A’s layover after 0728 is 16 minutes, not 19 minutes. (: Can’t
fault you cos it’s not easy to do schedules manually.
Some mealbreaks also need adjustments. 
3A can eat just that if swap the timing then the layover at Bishan
is just 5min only.
Nice one.
However, 2A and 82A cannot have 2 meal breaks, which is defined
as a break between 20 to 39 minutes. Normal layover should last
between 5 to 19 minutes.
Observe how 20S and 5P switch slots so 5P can have his meal.
(:
I think 2A and 82A swap for the AM Meal break period
pai seh TS overlooked that part lolz.. I didnt rectify the
problem in my copy..
