    I enjoy TMax 400 for long exposures at night. Even though Acros has better reciprocity characteristics, the TMax is two stops faster to begin with, which makes a big difference up to about 5-10 minutes. I shoot at the same EI as I do during daytime, which is about EI 250 in replenished Xtol or D76 1:1.

    This is true, again Acros is just simpler the first 2 minutes lol.

    Plus you are getting different contrast with the different film speed

    On what camera do you have a shutter that allows you to make an accurate adjustment that will increase an exposure of 1 second by 1/3 stop? Or an exposure of 1/10,000 second by 1/3 stop?
    Any LF camera... About as accurate as the full stops will be...

    That's not correct. While the film has a certain amount of contrast itself, the final contrast of your developed negative is determined by you.

    By changing developing time, developer concentration, developer temperature, and agitation, YOU ALONE determine what the contrast will be.
