Let us assume:

*       50 % TX/RX duty cycle (i.e. a 'run' station in a contest)
*       35 wpm
*       50 units per word ('Paris' standard)
*       14 relay operations per word (based on 'Paris', using full break-in
QSK)
*       35 (wpm) * 14 (operations/word) * 50% * 60 (min/hour) = 14700
operations per hour
*       2 million operations / 14700 operations per hour = 136 hours
*       136 / 24 = 6 days

Vacuum relay life is very roughly about three contest weekends

cheers,

Gerard, AA3ES
