I decided to put some certo in a 1 ml sample vial that had DaD + NA, and had just an incy weeny little bit on the bottom.
Put 7 sprays in it...and voila' Dad scented Certo
And for the curious and tedious 7 sprays is just under 1ml, and a "few dab" of mine are 2 -> 3 sprays.

Using this much has subtle effects and the scent still stays close.
Will keep trying this out though as Im not a big fan of the sandalwood scent.

Time to reorder my Certo.
Been also using Glace which also works well as a social and makes people chatty, but Certo adds a more romantic vibe, but not too sexual, for day/work use.

My 50/50 mix of Certo and Alpha Maschio has also been working well in a social environment.

Thanks for the great insight on Certo guys, very very helpful and looking forward in using it.
