As I was a game shooter, long before I ever shot at a clay target, I had perfected my gun mount (I think !) and had my gun fitted accordingly. My first Competition was a National event, and was a 50 bird English Skeet competition. I took my ONLY gun, an AyA no.2, 26" side by side. It weighed 6 1/4 lbs. I was given 50 Winchester AA skeet 9's in 32 gram and a few loose ones for any 'no birds'. I can recall the Referee being very patient with me and having to explain which target was next to shoot. This was in the days of single cartridge in gun, for the single targets, only loading 2, for the pairs. I can recall shooting 44/50 and I finished 9th. I also shot the highest score of my 'team'. Thrown in at the deep end, maybe, but that was it, I was hooked. I got paid to go and shoot, my cartridges supplied, and my entry paid for. What was NOT to like (apart from 32 gram AA's in a light S x S !) I shot gun down for both skeet and sporting, (NOT Dtl) and I still do to this day, except as age and eyesight have reduced my ability somewhat, I find that I am pre-mounting my gun for certain sporting targets.
So adapt your own style and if that entails a bit of gun up and gun down so be it especially if it works FOR YOU !
