Well yeah, but the diference between 14 and 7 is much greater, yet I got the same densities....same with the one at 3 min....the 3 min was only a bit lower...Essentially what my data is telling me is that this developer is only good for "normal" developement without being able to do expansion or contraction. Obviously this does not make sense....
