GET lists/statuses most recent Tweets


I have a list with 250 subscribed members.
And trying to get the tweets in specified time range using max_id and since_id params.
But usually get empty result set.
I found note that since_id param have limits to the number of Tweets which can be accessed through the API.
But whats the max count of most recent tweets I can obtain ?


I am Also facing same problem. Only i can able to access around 500 to 800 recent tweets , I cant able to go older tweets its returning empty result. (I am using max Id parameter to go for older tweets ). Any face the same issue ?.
