Terrific picture. Fascinating to look at in a photo. Maybe not so great when you're close. Glad you're safe!

1) Start at 22 filled - the given puzzle. Unique Possibilities to 26. (UP 26).
2) Hidden pair 24 at d2f3 forbids d2=16 and f3=789. UP 27.
3) Hidden pair 14 at d7f8 forbids d7=267,f8=28. UP 28.
4a) d4=7 == d9=7 -- a9=7 == a5=7 forbids b4=7.
4b) Locked 7's at ab5 forbid i5=7. UP 81
Totals sets: 7. Max depth 2. Rating: 3(.03) +.01 = .10

Nice chain Huaiyu!

You could write your chain as:
f8=4 == f8=1 -- b8=1 == b7=1 -- b7=7 == a9=7 -- d8=7 == d8=2 -- d2=2 == d2=4 forbids d7=4:

One could be shorten your chain to:
b7=7 == a9=7 -- d8=7 == d4=7 -- d4=1 == d7=1 forbids b7=1

What do the number chains posted here mean?
Eden  From Australia
You would be wanting to wear your brown pants in that situation.
NG  From Alabama
For Leeadi: I wish someone would tell me too! I know they are positions on the board but not sure how they are named or how to follow the above chains!

Martha: these were waterspouts, formed over water, as we were approaching the Sunshine Skyway Bridge, coming from the Tampa Airport
