Most of what I was going to contribute has been covered. Those who have met me know I have a full face & neck to shave and consider myself a medium grained breast with sub average to sensitive skin. The reason I went to wet shaving in the first place as carts, can foam left me with patchy dry, oily irritated skin and ingrowns.
So to answer the question, three to four times a week on average. Not weekends.
When I'm daily shaving I'll only do one pass and buff my problem areas like my chin, top lip and a spot on my neck. No ATG as my face will light up. I do ATG usually when I have a day gap between shaves.
What I have concluded is wet shaving is an art and your skills need to be honed, I'm two years in now (financially broke) and still learning.
Though I would like to boast, to a degree that I can now shave with any DE/SE. That is because and @Snooze only mentioned this last weekend was to stick to one razor and learn it till it is muscle memory. To boast again I have dozens and dozens of razors and I suck at all of them until I know how it performs and again as someone mentioned, what blade would work with it/what.
Using a very mild RR Mamba I still can get irritation as I'm applying pressure, bad blade combo and chasing BBS so still have not learnt its mysterys. Like wise the PAA Evolution it is the most aggressive out there & more so than the R41. But over time I have tamed it and can get a daily shave with this beast with none or low irritation. As I have forced myself to stick to one razor and just kept trying. What I'm saying is a mild razor is not necessarily going to get you less irritation. It's your technique. Personally like a mid aggressive razor with good technique gives me the best shave. Using less efficient razors makes me use a bad technique as i am not satisfied with the performance of it and tend to work it more by applying pressure and haste.
Though some days it doesn't matter what I use as I can feel my beard is not in the right mood. Sometimes when I wake up my stubble is hard and dry (seasonal) and know my basic warm water splash is not going to give me the best hydrated base to work with; and I'll feel irritated after my shave. No preshave is going to help here. To get around this I'll wet my face and apply sorbolene cream (stay away from the vit E added ones as cheap form of vit E used & is crap and can cause pimples). Then leave it on for awhile and do breakfast, get ready etc.
Ideally a warm towel would help but too busy to wait with a towel on face.
So why don't I shower then shave?
Since I'm hairy I shower after I shave. Ideally showering before softens the whiskers and relaxes the skin. I don't have this luxury as I have lather from my ears and down to my chest. Yeah you could say I'm doing it wrong but full breaded gents know what I'm talking about.
It's hard to give advice to others when your beard isn't the same or you are a goatee holder and give advice to a person who shaves their chin and lip under the nose. Hence YMMV.
Lather, as mentioned again by previous posts. So important for me. Wetter the better before it breaks apart or trys to run off my face (stays put), though each soap is different. It usually is at its slickest and hydrating point when it can take no more water.
Post shave I rinse my face to remove any stray cut whiskers as they will itch me later especially if caught in the upper chest hair. Hence the post shower.
The left over lather is then applied over my shaved face while I clean up the sink area and then I jump into the shower. This I find retains the skin's natural moisture and any beneficial soap ingredients can continue to perform. Added bonus is it acts as a hemostatic and relief for small nicks or razor burn.
Post is anyone's game. Personally like a mentholated splash and then a balm/ointment applied later after a few minutes or ten to absorb and see the splash benefits, seasonal based. As a sinner I'll apply a few drops of APR first into my hand then a few of a highly alcohol based no frills splash as a combo deal as I find the APR glycerine in summer is to heavy for me.
Know it's a lot so take what you want from it. Not telling you anything but hope something in the above helps out or makes you think about your approach or offer other techniques.

may God save the Queen 
I like to mix my shaves up trying different gear and despite having a tonne of sample blades to try - I normally stick with the brands that work out of convenience and being lazy/tired... Looking forward to my sabbatical in 2019 so I can use up my current gear and might try adjusting my shave pattern when necessary... Happy shaves!
skin - I'm like that, so I sometimes use Proraso pre shave cream or Coconut oil rubbed in prior to the lather. These have no ill affect on the lather if you have a good soap.
