Outside of getting equipment like Thermite Paste in Shadow Raid or setting up for heists and all that, how many of you actually dd use the Preplanning function for drawing out a plan?

Personally; I haven't used it that much outside of just today. My dad just picked up Payday 2 and he has been wanting to play with me for a few days, so today me and him started doing some heists. I personally am II-100 right now so I used as many skillpoints as my Dad had so we were both at 37ish skill points (Level 33-34) We first started off with Slaughterhouse (On Normal) and he was a bit confused, mostly because I forgot to explain what was happening to the heist, so I started up the next two heists; Shadow Raid and The Diamond (Dentist).

On The Shadow Raid; I decided to actually start mapping out an entire plan, even including the sewer and what the Thermite was used for, and going over everything from point A. to point B. eventually (After an astounding 10 tries because both me and him were sucking). But he actually enjoyed the time I used with it, so I went with the Diamond, since it is (arguably for me) the easiest Dentist heist that doesn't spoil plot with Hoxton; or on gimmicks. On this heist me and him both got through it on our first time and we followed our plan to pretty good success (with one minor hickup where I thought we would come up over by the stairwell where the Bag Man can be; and where we actually came out on the top floor.)

So, have you guys used Preplanning for what it was meant to be, to Preplan?
