man i am all day with my verses, cuz i literally dont want to stop untill i am satisfied, and you know how hard it is to satisfy yourself with your own work...i do my verses atleast 20 times easy...i even re-do my dubs and adlibs sometimes about 15-20 times...lets not even get to the hook lol, thats ridiculous...but umm i only punch in when i think it is needed, i have nothing against it..i usually design my verses in sections and punch in-in each section...it sounds good, works for me...i guess its different for everyone
