Well, it depends. When I didn't use coasting, it was rare to reach 3l/100km. When I started to do so, it became something basic, 'good' is well under that. Now 'good' is under 2.8l/100km. Very good is like 2.6-2.7. PR is 2.38 (I may not reach it again). But I need long trips and hills or mountains for the for 'very good' tanks, so I can't compare them directly.
Of course only a part of my coasting is P&G, but there are circumstances where P&G is a natural way to follow the terrain or the traffic, so I P&G there even when I don't do otherwise.
And I almost always P&G if I can't shift into at least 4th (topmost minus one).
And the main problem is that my bike doesn't have any kind of FCD.
Plus side of flat road P&G:
- A few percent FE gain over the bottom of highest gear. Sometimes more. Surely depends on the way you do.
- Presumably even more gain when in a lower gear (some FCD would help!).
- Keeps you awake after night shifts (no joking here
).
- The ability to choose which hand you want to rest (can really help when you ride all day long)
- Stronger grip in the long run
Minus side:
- Tiresome and takes a bit of your attention.
- Wears dropout bearing (though I really don't know how much - Teresa's lasted for ~111000km).
- Surely wears rear tire more than constant low speed riding.
