I need some guidance on what bike to buy. I have had a GURU fit as part of my shopping process and I also had my 2012 P3 fit using the RETUL system. I have attached the data from each of these fittings.

Here is my Bike story:

I'm 40 years old, 6'3" 210 lbs. My goal is a 6ish hour Ironman bike.

I bought the 2012 P3 for my first triathlons not really knowing what I was doing. I had a RETUL fit done after I bought it and I was not unhappy with the comfort of it when I was riding lots. I did an Ironman in 2014 on it then took off a year to build a house. I got fat while I built the house. When I went back to riding the P3 in 2016 I could not get comfortable on it anymore. I had a guy make me a pretty good offer on my P3 so I sold it.

I then went for a GURU fit to find out what would be the perfect bike for my old bones.

Heres what I am confused about the data from the GURU fit:

The GURU fit sheet states that my torso to Inseam ration is average, but the stack and reach recommendation is for a bike that has a tall stack and short reach. I thought that basically, the reach is a function of torso length and the stack is a function of inseam. I guess I thought if I was average in the ratio of inseam/torso I would be in the middle of the scale of bike stack and reach, but the fit recommends a reasonably tall bike with a quite short reach.

I have spent hours analyzing the data and the stack and reach of tons of different bikes looking for one that is right for me. I am probably over thinking this, but my concern is after spending $500 on fittings and ending up getting into another bike that is not right.
