Not an expert here, so with that in mind my advice is worth what you paid for it. Overall it looks pretty good. I wouldn’t stress about going a little harder on hills, but you might want to try to cut down on coasting time a bit if possible.
Just pedal and eat. If you are breathing the way you can talking it’s all good if you are after “pure” lsd ride. No matter what part of zone you are, Long element will trump all other aspects of your ride.
Ditto, I aim for 5% or less of coasting if possible. Just takes some shifting and paying attention on the downs that most people coast. You can hold decent wattage on all but the fastest downs (over 30 mph) from my experience.
A note about coasting: TR appears to include any time not spent moving as time “coasting” So, if you are stopped at a light, stopped to refill bottles, or stopped for any other reason, it is included in “coasting.” It was not immediately obvious to me that this would be the case, but it is.
