Say you are counting the number of decays and the time of observation is varied. I know that as time increases, the Gaussian Distribution becomes a closer fit to the observed probability than when the time interval takes smaller values because the mean count rate increases, but which is the better fit - Poisson or Gaussian?

I expect Poisson disttribution to remain the better fit throughout, as in this situation the Gaussian distribution can be derived from the Poisson?

Thanks
