For my RPM's I decided to go at whatever I self selected figuring this is what would test most efficient for GPA. I was on a computrainer to keep power more constant. Data was from pedals of course.
I just pulled up the data and here is what I had.

Your making me want to come back and try everything again in the summer when I have time. I'm 5'8 if you are wanting a little more info on me.
Side note- cracked my lock ring on the 155 in May and went back to the 145 for about 10 days. Almost raced on them but was happy to have the 155 back on.
Side note 2- When my bike was sent to Kona on TBB (legacy athlete so nothing to really brag about) I got my old TT bike that had the 165 on it (I let someone barrow it for several years). I had the position the same but felt terrible with 165. I had ordered another 155 and had it put on the next day and all way better. No data with that but figured I would throw that in.
I love seeing a person do some testing. And I love the sharing of inputs.
I have to say again, the biggest take away for me so far is racing, and training at slower RPM's. I have always shown it keeps my HR down. I can already feel how much stronger my legs feel at the slower RPM's. I have raced twice with a lower RPM focus and it felt so much better. And since in the first race I ran a 18 something off the bike for 3 miles, it, as one data point, did not seem to hurt my speed.
Your RPM stuff is way higher that I can hold. I started my testing with a 70 to 115 rpm. I could just hold the higher RPM without dying. Now, I was also in powercrank PC mode but still. And since I am doing so much testing now at 50 to 90 RPM, the 70 ish rpm just seems to be giving me the best "feelings", and a HR before it starts to jump up.
I still have no idea where this will end up, but I sure am going to have tons of data to try and see if I can find some cause and effect stuff.
Would love to see how your testing would go if you gathered data with a focus on finding the most effective RPM rate for you. I always assumed you had to have longer cranks for leverage, but with my testing, I sure can prove the gearing can be used to deal with hills, so far, need more data points. And I always had thought you had to spin high RPM's to be able to run off the bike well. So far, I again with my testing am finding this is not the case.
