Dari: Irregular present stems

[adorobrasil]

I'm trying to learn Dari with the help of some very inadequate textbooks and a few dictionaries/phrasebooks. I do have the help of two native speakers, but I sometimes seem to get contradictory information. I say 'seem' because I can't discount the possibility that I misunderstand the native speakers and /or differences of dialect and register. My question has to do with the present stem. Do all verbs in Dari have an irregular present stem like didan? If not could someone give a few examples of regular infinitive/past/present combinations?

A few examples of irregular present stems.

diidan >> diid >> biin (to see)

nishastan >> nishast >> nishiin (to sit)

saaxtan >> saaxt >> saaz (to make)

A few examples of regular present stems.

aamadan >> aamad >> aa (to come)

xandiidan >> xandiid >>xand (to laugh)

daviidan >> daviid >> dav (to run)

Well, that is extremely helpful. Some are regular. Perhaps this was causing some of my confusion. Knowing this will undoubtedly help me build my list of present stems. Tashakor!
