I only do hill pulse and glide by pulsing up and gliding down. When coasting I switch AC off as it the engine is less efficient when idling.
No mods on my car, only folding passenger mirror on long highway trips.
Until now I have owned the car one winter and got 48mpg (4.9l/100km) which is not bad with short trips uphill to the ski resorts and winter tyres. I am hoping to meet 3l/100km mark this summer with long holiday trips on secondary roads (80-90km/h). With winter tyres and longer trips (30km) I can already get about 4L/100km (58mpg), thanks also to the very good aerodynamics (0.59m2 measured by me thanks to Matlab).
I'd be happy to try front grille cover, but I am not very good with my hands and do not want to put something with no good finish on the car.

In post #4 I stated that I will run the A/C full blast on a 7 mile downhill near me to increase engine braking effect (or heat and wipers and rear window defroster in winter). When I am E-On coasting the A/C and all accessories except the radio are off to reach the highest mpg during the glide phase.
It looks like you are already getting great mpg in your Octavia. I believe it is similar to the Golf AllTrak that we can get here in the States. I used foam pipe insulation (it can be purchased in black) and pushed it between the grill bars on my Golf. I think it looks pretty stealthy and is easily removed if needed.
I fold my driver’s side mirror on the highway and removed the passenger mirror completely. I have small convex mirrors on each side but do head checks too.
