It is additional buffer stock.
Actually HKT has accepted your propose.
But it caused base on Seger's capacitor does not have any issues.
However their capacitor had a big issue & not yet solve it.
History has already changed.
We understand your points but I need to say that is history.
We did intend to keep buffer stock as they were and have done this for quite some time.
Unfortunately this is no longer possible due to the reason of capacitor & not enough durability.
