I didn't realise it was a problem for you. Just throw them in
The thing with the 30 strings is that when you start reviewing a contribution as a maintainer, it is nice to be able to do the job in one go. It's impossible to estimate how long the review is going to take. That depends on the number of inconsistencies, spelling / capitals / punctuation-mistakes...etc.
Most of the language pack maintainers are volunteers, often squeezing translating/reviewing in between other jobs, while waiting for some process to finish (speaking for myself here ). A 30 string contribution will probably not take longer then 10 minutes of work to review, even if there is some rework to do or if strings are very long. A 100 string contribution can take 30 minutes, so I don't start on it unless I'm sure I have that time without interruptions en no other work that can be done in 30 minutes.
So short contributions will be processed in hours or days, longer contributions can take a lot longer.
