as rapidly as

[azz]

a. As rapidly as they are moving, they'll be here soon.

b. As hard as John hit Henry, Henry must be in a lot of pain right now.

Are the above sentences grammatically correct and meaningful?

I am confused.

Generally, when 'as' is used like this with adjectives, the meaning is usually 'although'.

c. As precise as this instrument is, it sometimes gives wrong readings.

I don't think that could be used in a 'positive' sense.



Many thanks

Yes, the sentences are semantically strange.

--> Moving this rapidly, they'll be here soon. (etc.)
