If that is the case, would there be a reasonable convention to make this clear? 

In a nutshell, in such a review the possible interpretations are
* I reviewed, but didn't feel qualified to do the rest
* I reviewed, but did not get round to give it full attention
* I reviewed, but before I make a final decision want to look at the next 
version
...
* I reviewed and don't object the rest
* I reviewed and agreed with the rest 
The latter two are equivalent to Ack/R-b

That is quite a large range of possibilities and kind of leaves the author 
guessing what state the review is in

Regards
Lars
