Optimal pace of speech
You will generally get the following guidance if you take courses on presentation skills (this list from write-out-loud.com)


Slow speech is usually regarded as less than 110 wpm, or words per minute.
Conversational speech generally falls between 120 wpm at the slow end, to 150 - 200 wpm in the fast range.
People who read books for radio or podcasts are often asked to speak at 150-160 wpm.
Auctioneers or commentators who practice speed speech are usually in the 250 to 400 wpm range.


So you'll probably want to aim for that 150 wpm range to be able to get a reasonable amount across, but not sound like an auctioneer
