Mechanic rate of fire question

[pyrozeal]

How many times does a mechanic hit per minute in tank mode and siege mode?

I know that visually we see 3 missiles x2 coming out per attack (showing 6 numbers), but how many times does it spam this set of 6 per minute, and how much faster is the rate of fire for siege mode?

For corsair's cannon (with booster): 95.23 times per minute (60,000 ms/ 630 ms)
The 630 ms is the delay per attack for a corsair's cannon.
What is the delay for a mechanic's tank mode? Siege mode?

18-20 siege attacks per the 5 second duration, from what i've seen posted elsewhere.
