Six weeks into jelqing

Hi everyone, I’ve been doing PE for about six weeks now. I just wanted to know if there’s any changes I could do to my routine to improve it, and whether it is a good routine to be following. I aim to gain both girth and length.

My routine so far:
.Warm up for ten minutes with a hot flannel, reheat after each minute, as I reheat the flannel I do a v-stretch.
.Usually I would start to wet jelq with vaseline but recently I started to do some more v-stretches before I jelq.
.Next I jelq for 10-15 minutes, from 50%-80% erection, with vaseline.
.Afterwards I have a hot bath.
.I do this two days on then one day off.
(I have been doing this routine for about four of the five weeks, when I started off it was just jelqing for a few minutes to get the hang of it ect)

.So far I have noticed my erections are harder and I believe I have gained about 0.2 in girth but I need to make a more accurate measurement.

I started off :
6 inches when erect
4.5 girth when erect
