Its been almost 2 years since I asked this question and my fit has changed drastically over this period. I just thought i should share some nuggets from my journey.
Bike fitter 1
He raised my saddle height by 4.5 cm, swapped 130mm giant contact saddle for a 155mm bontrager aeolus saddle, cleats were positioned a few mm behind my 1st mertatasal and it was happy days. I rode that position for a year with out any major issues. But there was this niggle on my left knee ane I alson got a new bike which I wanted t9 setup. So I approached bike fitter 2 as bike fitter one was nolonger operational.
Bike fitter 2
He simply replicated bike fitter ones fit, and reduced my handlebar drop to open up my hips. He also moved my cleats further forward and that led to major discomfort. I simply moved myself back to the previous fit. I know what you may be thinking, give it time so you can get used to it. Trust me that fit was garbage. Cue bike fitter 3
Bike fitter 3
This dude almost ruined me. He staggered my cleats, raised the saddle a few mms and tilted my saddle like a MF. I am talking -8.5° of tilt from tip to tip and bare in mind Bontrager recommends about -2° of tilt. The position was so aggressive I felt pro for a few months. I was never the most symmetrical of specimens but I am convinced this fit really messed up my pelvis. I developed an extreme muscle imbalance, pelvic rotation, extreme anterior pelvic tilt, yeah I became a mess. I returned myself back to the bike fitter 1 put me on. I felt comfortable on the but could still something was not right.
Bike fitter 4.
I saw this dude because I was trying to sort out the assymetry had developed. He confirmed I was sitting skew on the bike, proceeded to Google what could be causing it while I was perched on the bike like TRex. After finding no answers from the great Oracle. He simply rotated one of my cleats and charged me R700 bucks and said I must go see someone to help figure out what was wrong and come back. I saw a Bio but didn't go to Mr googler because I just didn't have faith in his ability. Cue in bike fitter 5.

He made some changes ,same saddle height as bike fitter 1, a more chilled saddle tilt but moved my cleats further forward than ever before and reduced my stem from 100 to 80mm. In hindsight, I learnt that my body can adapt to extreme changes because I was able to ride a sub 3 cycle while riding on my tippy toes.
As I land. This is where I am now. Throughout this period I have been consuming an insane amout of bike fit content which I started applying.
I moved from 172.5 to 165mm long cranks. It felt strange at first and I couldn't produce any seated power especially on climbs. Tweaked my setback and now I am at home.
Saddle went up from 81cm to 81.5 because of the change in crank length.
Got a proper seat measurement of 125mm and I now use a 140mm wide selle san marco saddle. I run 10.5 cm setback, 3.8° of tilt. A big bum doesnt always mean a wide saddle is required.
I shoved my cleats all the way back in my shimano shoes. They now sit 2cm behind my 5th metatarsal. Tweaked my cleat rotation till all the medial and lateral knee discomfort vanished.
I am on an exercise plan to restore balance to my hips and strengthen my weak left glute and hip flexors which contributes to my assymetry.
Using specialized blue footbeds. They felt strange at first but I now feel support throughout my entire foot.I started with the red and moved to the blue a few months later. They can take a bit of time to get used to.
With these changes I have moved myself from a 44%L/56%R to a 48%L/52, stabilised my hips with the right knee not collapsing as much.
