I have no idea what's going on here. I'm getting far left impacts again during the off season when I shoot heavier bows.

I've been taking slow motion videos to try and diagnose it. Nothing looks wrong with my followthrough, no plucking and my hand goes straight back as usual. I always make sure the pressure point of my grip is at the base of my thumb and my bow arm isn't hyperextended

The only possible thing I can see is that the bow twists to the left after the shot but it looks like the torque is happening after the arrow already leaves the shelf. Could it be possible I'm torquing it enough to still send the arrow left but it's not obvious on the camera?

Take video of yourself from high behind you. Sounds like you’re not into alignment.

Im an odd duck with my own issues but think some of what Ive learned of myself may apply here.
Although a bit counter intuitive. After chasing random left misses last year with my hunting weight bows I narrowed it down to face/anchor pressure. When I dug into my face I almost without fail had a left miss. I resolved this last year by giving up on string blur and settling in a light anchor without pressure or head movement.
Beyond that I will get misses left due to clothes contact.
When my bow arm goes left I believe this is due to improper alignment. When I am at what I believe to be proper alignment for me. I look for only forward movement from my bow/bow side.

I get left misses with longer bows due to pectoral string contact. I have to hunch out a little, esp when wearing bulky clothes. This is great for alignment and mobility anyway. Canting solves this too but I don't do that. Lack of back tension can result in left misses for RH archer due to string hand plucking to get away from the string. This may be your problem. Even high bow shoulder, poor alignment, can too.

I personally would go down to a light bow and analyse what is working and replicate it on the heavier bow, the whole sequence in detail.

What means “heavier” for you. A heavier bow will compress your frame / alter your alignment at full draw and what you think your draw length is it’s not under a heavy bow. An arrow you think is good based on the calculator actually is stiff for your DL, hence arrows hit left.

 

[Remote]

Yes, if you aren't even reaching full draw then that's another thing entirely and Draven's comment would hold true. Then you would be overbowed.

Have you gone over all of these?

The bow is only 5lbs heavier. My draw length is the same as it is under my lighter bow. Also it definitely has nothing to do with the spine because I'm shooting fletched arrows not far away and the amount it's impacting left definitely has nothing to do with the spine. The dynamic calculator has also always been dead on with my bareshafts

I'm not getting any plucking or clothing contact. My bow arm shoulder is also nice and low and not collapsing. My alignment also looks spot on too.

If you think you are doing all the same film yourself from above with both bows at full draw to verify alignment and take pictures of how much the arrow is past riser when at full draw with both bows. If none of above are saying something to you, believe what you write and ignore what I said. There can be other reasons just you can find.

PS Are you still using fixed crawl? You went a spine up from your usual setup?

I've done that as well. Maybe not from above but I put a piece of tape on the arrow and film from the side and back. I'm still using a fixed crawl still but much shorter as I changed my anchor point to be a bit higher so my crawl is only 0.75". However it's not necessarily my anchor point that's the problem as this has always been an issue

I also used to have that issue with focusing the string blur. That's why I switched to an anchor that's more to the side of my face and that fixed my forearm tension.

Buy or make a Formaster, it'll tell you a lot. I need to make myself another one.

 

[r_davis]

Definitely need to shoot some video from above to verify that your alignment is good. It sure sounds like this may be the problem.

If you are torquing on release then that means you are responding to a force in the direction of the torque. It's like a tug-a-war. If the other team lets go of the rope, you are going to fall in the direction you were actually pulling. You may not be as balanced as you think you are.

I had a tournament where suddenly, everything was landing on the right side of the target. I knew I was dropping my bow arm but I could not figure out why.

I had to go back to fundamentals and focus on my shot cycle and form. Some of these issues are too subtle to see. Trying to identify the problem may lead you down a never ending rat hole.

The problem with video is that you can force your shot to "look right". You can guide a follow-through without be aware you are doing it. Also, the follow-through is only half the shot. If your follow-through looks correct but your bow are is moving then you are not in balance.

A key lesson I got from Sandy McCain was to focus on what you want to do rather than what you are doing wrong. Revisit your shot cycle and focus on executing each step the way it is designed.
