As I see it, and I'm not the final authority.. only a CFIG with a few other
power ratings thrown in:

(2) 200 hours of flight time as a pilot in heavier-than-air aircraft and at
least 20 flights in a glider as pilot in command, including at least-

(i) 3 hours of flight training in a glider or 10 training flights in a
glider with an authorized instructor on the areas of operation listed in
§61.127(b)(6) of this part including at least 3 training flights in a glider
with an authorized instructor in preparation for the practical test within
the 60-day period preceding the date of the test; and

(ii) 5 solo flights in a glider on the areas of operation listed in
§61.127(b)(6) of this part.

Moving from Commercial Power to Commercial Glider, you need 200hrs power AND
20 flights as Glider PIC. You are correct, you cannot log PIC while taking
dual instruction. IF you had a private glider rating, then you could log PIC
and DUAL received at the same time. If you have prior Pvt Glider experience,
the 20 PIC flight would not be an issue.

So, once you have solo'd, you need 20 PIC (solo) flights, and 5 of those
should be logged as preparation IAW 61.127(b)(6).

Also, 3 of 10 of your instruction flights have to be within the last 60 days
prior to check ride and logged as prep flights.

I've found by experience, that depending on the past experience of the
candidate, that at least 20 dual flights are need in a Grob 103 just to
complete the required training events and get the landing "down pat" to solo
standards. Pilots that have only flown jets have the hardest time. Propeller
pilots with tail wheel time have the easiest transition.

I'm looking at adding a commercial glider rating this summer. Never been
in a glider, but my hunch is that it will be a good learning experience
even though I'll never fly one for hire.

So ... trying to divine the meaning of Part 61.129(f)2

"20 flights in a glider as PIC" and "5 solo flights"

But ... I can't log PIC time while getting dual instruction since I'm not
rated in the airplane. So, I'm really looking at 20 solo flights. Right?

(The only way I could see someone having 20 flights as PIC and but only 5
solo flights would be if the person had a fairly new Private glider rating
and then took dual for the Commercial. Right?)
