I could publish my own research calculator if anyone's interested.
Here is a screenshot:
It does more than just calculate the end version. It will also provide other usefull information to help decide how to set up your research.
It's a little win32 application. But if there's demand for it I could easily port it to gambas2 for the linux users.
I've been using it for a while now and I couldn't do without it anymore
BTW..... the calculated end version is not 100% accurate (it seems to have the same small rounding errors as Emi's version) but I can assure that there will be very small difference.
PM me ingame if you want me to provide a link to the download location.
