Tend to agree with Silvaire1 as to why. Can I ask if you thought the take off ground roll was longer or shorter than your 'normal'?
I used to do the same, raise the tail early to get the fuselage pretty much horizontal, accelerate then positive pull back to unstick. Then I was told that for the shortest t/o roll to just lift the tailwheel out of the grass and let her come off when she's ready. Just about halved my ground roll.
I would not suggest this method for a taildragger with a ground attitude close to it's stall angle but many aren't like that, and it does require a little finessing just after take off.
