Hello!
Thanks for the interest in NodeXL!
Twitter’s API data volumes can vary based on factors internal to Twitter.
NodeXL will execute the same calls every time, but Twitter’s results may vary.
We do find that in some cases a delay of 24 hours will return the volumes delivered by Twitter to higher volumes.
Only a commercial feed from Twitter can guarantee a sustained rate of data. These services are currently very expensive.
If you would like to share the query you are running, I can try to replicate it here – perhaps I will get more data?
Regards,
Marc
