This is called wisdom (or experience). I do about the same. Make certain everything transferred properly, back that up then delete. If it is an important job I even set the SD card aside in case I find hidden flaws along the way! This is why I miss film (sometimes). If the shutter fired, then there is SOME THING on the film! Processing still could cause issues though!
