[BioC] edgeR: Value of variation of biological variation (BCV)

Dear edgeR users and R community,
I'm analysing a set of RNA-Seq data which has 2 different genotypes
(treeHS, treeLS) and time of treatment (0H, 3H, 24H, 96H) with edgeR.
After carried out estimating the common dispersion, the value of BCV
for my RNA-Seq data was 0.428.
> hl <- estimateGLMCommonDisp(hl, hl.design, verbose=TRUE)
Disp = 0.18319 , BCV = 0.428
May I ask, it is common to see the value of variation of biological
variation (BCV) as such? What this value can tells about the RNA-Seq
data? I have these thoughts wondering me for a while. Forgive me if I
have asked a stupid question.
Thank you very much for your time.
Have a nice weekend.
