Mercury square/ Moon square (What if the planet goes 'its fall' or 'retrogate' during the square)

[JeraOpus]

Regarding moon square: What if someone starts the square when moon is not void but some day while doing a certain number it's done when moon is void and/or goes into Scorpio [its fall] or Capricorn [its detriment]

Regarding mercury, It's the 2nd fastest moving planet after the moon.
Quora link for the reference
PLANET CYCLE TIMES (AVERAGE CHANGE OF SIGN)
Mercury - 1 year (1 month)

But the bot is telling:
Mercury: About 14-30 days in each zodiac sign (varies due to its elliptical orbit)

Can someone confirm which one of the above is correct?

Now, coming to the question.
The sqaure of mercury is for 64 Days.
If someone starts their Square in Capricorn, then there are 2 zodiac signs (Capricorn and Aquarius) before the planet goes into Pisces [its detriment].
Even if we consider the 30 days (per sign) for mercury (which is unlikely every time), we still end up with 60 days, considering we start the very first day Mercury enters Capricorn.
Planet will still go into Pisces (its detriment). Will this cause any problems?

The above is for mercury, and there is a good possibility other planets will do the same (I haven't checked every planet yet)

Spells or Squares, cannot be started during the “moon void.” If it occurs after starting it is not a problem.

If the planet goes into Detriment, Retrograde, or falls in the later days of the square, will it cause any problems or only starting the square when the planet is in home sign matters and if the planet goes into Fall, retro or detriment after starting in the home sign then it doesn't matter?

All the squares shouldn't be started during 'moon void' of just the moon square (Beause that's the only chakra affected by the moon) or (The during the void moon, the intuition will run wild and will imprint specific memory during the process of doing a square, or is it something else?)

The important thing is the beginning; the later is not “relevant.”

All squares must not begin during the “moon void,” for the same concept as the “rules” on spells.
