Has someone done the math on 0 deltas yet?

Going off rough estimates:

Trump has tweeted exactly 12909 times since Q started posting

There are 3800 Q posts (nov 2019)

Days since Q started posting: 828

Averaging to roughly 15 POTUS tweets

and

Averaging to roughly 4.5 Q posts per day

since Q started posting.

Lets say we consider anything within 60 seconds (one minute) of another a zero delta

ignoring things like more active posting hours, the probability that Q and POTUS post within one minute of another, on any given day, on average, is:

Probability that POTUS posts during any 60 second interval: 15/1440

Probability that Q posts during any 60 second interval: 4.5/1440

Probability that both happen at the same time for any given 60 second interval:

(15/1440)*(4.5/1440)

Times 1440 to get the probability of it happening on a given single day:

(154.51440) / (1440*1440)

Times 828 to get the probability of it happening since the time Q started posting:

(154.51440828) / (14401440)

Results in an estimate of around 38 expected zero deltas in a 828 day period.

Does anyone know the number of confirmed zero deltas?

Also any mathfags want to check my math, might be wrong.
