I would expect more than one or two. There's plenty of analysis available about the penetration of messages. If you start with "Flight 123 to London now ready for boarding at gate 45 ......" everyone is then getting up, assembling bags, marshalling their children, walking to the queue, etc - normal behaviour in this situation, and so the rest of any message will likely be lost. You have to put the messages one at a time, and when the pax are most likely to have their BC in their hand so they don't put it away again. Hence the prominent notice at the gate approach.
