Ah, I see. The docs say "Although this result format does not have as much information, it may be easier for existing solr clients to parse". I guess the ngroups value could be added to this format, but apparently it isn't. I do agree with you that to be usefull (as in possible to read for a client that doesn't know of the grouped format), the number should be that of the groups, not of the documents.
A quick glance in the code learns that it is indeed not calculated in this case. But not completely trivial to fix. Could you use format=simple instead? That will work with ngroups.
