diyrecepiebook dot coms recipe calculator is Seriously Flawed !

Whats wrong with this picture (screen shot)
a picture speaks a thousand words.
18% flavorings total.
60mg 50/50 pg/vg.
target ratio 70/30
target nic 30mg
batch 100ml (to make the incorrect mixing instruction numbers more obvious)

It even claims its an impossible mix, stating that the vg is a negative ? ... ?

Try it out for yourself, then move the ratio slider to see another target pg/vg ratio...wow this math is sooooo wrong !
I tried to bring this problem to the attention of the site operator about a month ago, but really didnt get much in reply and the problem math is still there.

Have you tried the ejuice me up cal?

ejuice Me Up all the way!

I have yet to find something better.. everything else is either to simplistic or over the top. Only thing I wish it had a cost calculator built in and the ability to use more then seven flavors. Can't store all my recipes in it for this reason but overall it's solid.

Thanks danny and crank, but i'm really not looking for a calculator "advice" so to speak.
I can do the math in my head most of the time, or I'll run any of several xls spreadsheets or the online ecigvape dot com selection of useful calculators.

I'm just pointing out that the calculator at diyrecipebook.com IS seriously flawed if you're looking for accuracy in the target pg/vg ratio selector function.I should have uploaded a larger screen shot, but anyway in this example it is giving an 74.9pg/25.1vg where the slider is set for a 70/30 target ratio. It warns that the mix is impossible to accomplish where clearly it IS totally possible, it claims that the vg is a negative value (not), while it would be very simple to arrive at any of several ratios by simply adjusting the plain pg and vg additions. That ratio selector slider bar function is clearly broken and useless.
