Newbie draw length questions

[dingo007]

Hi,
Ive recently bought my first bow, i live along way from a archery dealer so i brought one online.
I got a hoyt torrex and really enjoying this hobby despite steep learning curve. I try practice every day morning and evening.
Im still trying to find my draw lenght, by calculations its 27.5 this gave me lots of pin float and was easy to pull back at 70# but thought it could be to short so I increased draw length to 28.5 and now i can target a object without so much float, feels so much nicer but harder to pull back so i dropped poundage to 65# till i get used to it. i can straighten my forearm out now too as a lot of YouTube videos illustrated. anchor points feel good, ear lobe, jaw line, nose on string...
Ive no idea if im doing it right? but if i shoot better it should be ok? i can get good groups out to 40m even robin hooded a arrow working on my form(so hilly here i cant shoot longer here to test).
Am i doing this right?
Thanks in advance!

It's worth the time and $$$ to take it to a shop who will tune/setup it to you. I cannot stress this enough.

im over 1000k round trip away mate, not a option. im sure ill meet other archers here once it cools down, the tourist will flock up here... wish i could sometimes, but ill work it out like we did before shops
