I have backtests through 1992 and I think they are absolutely necessary. The more market conditions you can survive through.... the more realistic your assessment of the EA becomes. A few months testing only shows market conditions for a few months, which is sure to change.

As you rightly say, market conditions are sure to change within a few months!
So what is the point of looking back years!
