Thoughts on Group Leader
The group leader (Giovanni) was very good, very welcoming and a source of a lot of local information. However, his estimations of how long to this point or that were a bit loose (aka totally unreliable). There was a driver (Simone) who guided the cycling some days, and he was also very good, lots of local knowledge and way more realistic about distances.
Advice for Potential Travellers
If you don't like descending, don't forget that what goes up hairpin bends must come down hairpin bends. The grading of moderate is applied to the whole trip, but some of the days were way beyond moderate in terms of long ascents. The description of the surfaces as "10 percent easy gravel roads" is so far off the truth - steep in places and very bumpy with large chunks of rock is more like it. Nothing I would describe as an easy gravel road. If you are not sure about the climbing I'd suggest getting an e-bike. I had one and although they are VERY heavy it made going up a pleasure.
