He won’t ask before being fed at 10:00pm

This is Chacha
He often asks (meows) for his dinner at night time
Over the next 45 days, I'll record (and plot) what time he asks for dinner each night.
The option with the most number of days where he requests dinner at that time wins!
I'll also record and plot what time he was served dinner each night (which l suspect influences his next dinner demand time).
Data will be posted once a week: https://docs.google.com/spreadsheets/d/1pxtC2VdrnQ-Bgs6e35W1HKEwGKnLDRm77b0bd707IwA/edit?usp=sharing
Feeding rules: he will normally be fed in the window of 8:30-10:00pm. Generally, he will be fed ~20 mins after meowing (with a minimum at 8:30pm, and maximum at 10:00pm). However, if I am not at home, he may be fed later or earlier, which may act to reset the system.
His dinner consists of some wet food, and some dry food (my friends claim he's spoiled), weighed to the same amount.
