Questions about perfection & timing

1
Question 1:

Say Mercury is at 3 Libra, Jupiter at 10 Leo, Venus is at 28 Leo.
Nocturnal chart, Merc and Jup in triplicty.

They apply to a sextile at 12 degrees, the orb to the sextile at the time of the question is 7 degrees.

Here is the interesting thing, by the time they perfect, Venus enters Virgo and gives Mercury an MR. Would you count this? (In terms of giving Mercury a boost).

Question 2:

Mars and Venus are applying to conjunction orb of 7 degrees. Yet, they do not actually perfect for quite a long time as both are moving fast.

Venus at 13 with Mars at 20 Pisces, yet they do not perfect until 1 Aries.

They are within orb (7 degrees) yet the perfection for Venus at least is 18 degrees before perfection. How would you interpret this? (a long chase?) If they have 7 degrees orb, 7 days, or is it the 18 degrees/days until perfection?

Question 3:

This derives from question 2 actually. Perfection of two planets within orb, but in the following sign/house. Does anyone have any first hand experience with this one?
