Can you explain in simple terms why cocking the shutter first is likely to give a speed that was not what was intended and what speed are you likely to get. I have an Agfa Isolette I with 3 speeds(1/25th, 1/50th and 1/200th)If I have cocked the shutter with the speed set at /25th what speed am I likely to get?

With the Agfa I am not clear how not to set the speed before cocking the shutter. If the correct exposure is 1/25th for the forthcoming shot and was 1/25th for the last shot as well what exactly should I do to get the correct speed?

Are you saying that each time I should cock and fire the shutter first then do it all over again. I am not clear why this is prevents the problem you mention of getting the correct shutter speed. I presume that this requires a lens cap so no light hits the negative?

I am somewat confused as you will see. I may have misunderstood the first part of your post completely
