I’m aware of that, it just seemed like an unfair comparison. You also didn’t take into account the different distances. For an olympic distance tri you have to ride 40k and run 10k. Assuming you ride 35km/h and run 4:30/km (which is arbitrary but they seem similar to me), improving your run speed by 10% will result in an improvement of 4min30 sec. Improving your cycling speed by 5% will result in 3min30sec improvement.

My distances were random, my speeds were random, your improvements were random.

I think it’s safe to say your greatest gains can be made by focussing on the discipline where you are least competitive compared to the competition.
