The concept of BVA is to figure out whether the observed broadness of FRET distributions are owing to the molecular dynamics, by comparison of a calculated standard deviation ($s_E$) of FRET efficiencies for sub-bursts ,comprised of \textit{n} consecutive photons within the burst, from a mean FRET efficiency for a burst to an expected standard deviation($\sigma_E$) based on shot noise limited distribution~\cite{Torella_2011}.   If the broadness originates from different molecules with static but different FRET efficiencies, $s_E$ of each burst are is  only affected by shot noise and will follow a binomial distribution. However, if the broadness is from dynamics of single biomolecules, $s_E$ of each burst has to be larger than $\sigma_E$.  $$ n_t = n_a + \gamma\,n_d$$
