Would the area under the graph represent the average value for acceleration multiplied by the time, and hence the final velocity?

The area under a graph is the product of the X and Y axes.
So, if acceleration is in units of metres per second ^2, and time is in seconds, multiply seconds by metres per second ^2 and you get metres per second, which is a velocity. Why you would want to plot acceleration against time, I don't know. Don't forget that anything slowing down exhibits negative acceleration so the plot on your chart will go below the axis.

Thanks for the replies. It makes sense... even though the acceleration is considerable, the velocity is small because the duration it acts over is small as well... which reflects observations. We just need to upgrade the measuring stick so there's better detail in the results.

Wondered what that was that you wrapped around your head

Needless to say Rich is the nearest. Actually, using the traditional (when I was a kid) notation
v = u + a * t so a * t (the area under the curve) is the accumulated change in velocity (v  u)

No need for modesty, Dave. It needs saying...
