Does the following sentence with "however" make sense? [closed]

Solution 1:

Yep, it makes sense, and is common.

That said, if I were being pedantic about it, I'd prefer your "no matter how" over "however" in this case, because "however" is more formal, and makes it more obvious the next word should really be "slowLY", whereas the informal "no matter how" seems to work just fine with "slow".
