My thoughts are that you will add more. Each message on the queue may
have multiple addresses. If you split, then you will add to the number
of messages on the queue that sendmail must process. 
I'm not sure of your traffic, but the BLU server has 29 listservs, and
one of them has about 2000 members. One of our busiest has about 200
subscribers yielding about 150 messages a day. we use postfix as our MTA
on Red Hat Linux 7.1. The platform is an older Compaq Proliant rack
mount server running about 400Mhz. Yesterday my mail queue had over 300
messages waiting because two of our recipients on multiple lists had
their host taken down and another two on another list had invalid
addresses. Postfix seems to handle the queue a bit more effectively than
sendmail.
