Very noticeable that the SA ladies are doing very well, plenty of representation in the top ten teams, well done so far !

The difference between the 10t and 11t is quite impressive. Running a 38 11 is similar to a 34-10 (3.45 vs 3.4). Running a 36-10 gives you almost the same ratio as a 40-11. I have found the move from 11 to 10 on my gravel bike pretty impressive, and I was considering moving up a chainring size before but now I am pretty happy. 

Now don't get me started on the drivetrain inefficiencies of running a smaller front ring or a smaller cog on the back... 

 

 

forget about the drivetrain inefficiencies. That's so small its only noticeable to snake oil salespersons

Well if they are running 55t + chainrings in TT's partly to stay in the middle of the cassette, and people put on OSPW, wrapping your chain around a 10t and having a small front ring does not sound like the optimal combo. You are right though it is probably only milliwatts.

Its more the straightness of the chain were there is additional friction losses but I think unless you are addressesing all other friction losses the chain wrap over a 10 is nanonwatts and a watt is a small number

Believe it or not; that 1w over 4hrs is a fairly big loss of time when calculated and power. 
1 of the reasons we had Tadej run a junior cassette at the Tour TT last year to eliminate any cross chaining

That reminds me I should probably fix my rubbing brake before Sunday lol

It’s one of the reasons I select my MTB chainring more to keep the chain as straight as possible in the gears I need on the flats and rolling hills than big steep climbs or descents. 
On a road bike I apply the same. What gears are used mostly so what chain rings allow that while keeping the chain as straight as possible most of the time

Get an E-13 cassette and you can rock a 9t on the cassette

Best in line chain / chainring / cog = SS

Nope .. nowhere near as efficient, but serious street cred

Of course! #MulletPower is a thing. My guess is at least 40 Watts advantage!

Yes, please! At 80 RPM that is almost 4km/h faster then the 10T.
