This is normal behaviour. The dots are printed one per second, so
they give an apprximation how long the erase takes. It is normal that
it will take longer and longer the older your flash gets (i. e. the
more rease cycles it has gone through)

In this case the increase was approx. 15% which is poretty long;
either your flash is brand new (burn in phase) or it's pretty old
(near end of life)?
