No, I haven't seen that data for my boiler but it would be useful. Even though cycles might be shorter, note that the temperature that the whole system is exposed to is much lower on average. A typical boiler will run at 70 degrees, compared to mine at about 40-45.
Almost certainly yes. It's entirely possible to make frequent cycling reliable, but it costs more. Higher cost is bad when the decision process is essentially "sort by price and pick the lowest."
