I've pored over the rules and this forum and still am not sure I am counting total segments and continental flights correctly.

My understanding is:
- You get 20 sectors total (transfers do not count double)
- You get four "flights" in a continent (once again transfers would only count as one "flight)
- Intercontinent overland travel is counted as one sector but is NOT counted towards the intercontinenal 4 flights
- Intracontinental flights count in the 20 sector limit but not the 4 continental "flights"

So for the following itinerary I get the following counts (totalsectors/continenal flights):

exit SFO
UIO (1)
EZE (2/1)
GRU (3/2)
overland (there do not seem to be any connecting flights) to
GIG (4)
CDG (5)
CAS (6/1)
TLV (7/2)
overland to
IST (8)
BUD (9/3)
DBV (10/4)
overland to
CDG (11)
BKK (12)
DPS (13/1)
DEL (14/2)
HKK (15/3)
PER (16)
SYD (17/1)
AKL (18/2)
PPT (19/3)
SFO (20)

I have completely ignored transfers and any flights "via". I hope this is correct as it differs from the Star Alliance plan with which I am more familiar.

So, is my sector / flight count correct? Is this a valid itinerary?
