That's kind of interesting. By having an 11-32 instead of the 12-29 I'm using the shift pattern looks a bit better. You're double shifting from 16T to 20T whereas two shifts from 16T takes me to 19T.

Looking at the gaps in my gear range a little closer I see that I'd probably get optimal shifting by going to the big ring from 17T gear, where a double shift would take me to the 21T cog so 34-17 (53.5 gi) goes to 50-21 (63.7 gi) for a 19% jump. If I wait until I'm using the 16T (34-16=56.9 gi) the 1 up+2 down shift takes me to 50-19 (70.4 gi), a nearly 24% jump.

As a table with gear inches....

OK, yes, it is clear to me how much I'm overthinking this, but that's just putting numbers to what feels wrong on the road.
