Groups shifting high?

[JPeters218]

So I got the wife I to archery about 2 years ago now. Shes a pretty good shot, but now that leagues are started again, I was reminded of a problem with her shooting that I haven’t been able to figure out.

She always starts out good, (4’s and 5’s on a 1 spot), but once we hit about half way through, her groups start shifting high: like up into the 2’s. It’ll start with an arrow or 2, but soon her whole group will be up there. Still a good group, but just 6” high.

I know it’s not her sight, because we don’t touch that, and it’s always dead on to start the next week. She’s too new to be able to know what she’s doing wrong. And I’m a good shooter (typically mid-upper 290’s on a 5 spot), but I’m not great at watching someone else and picking out what they’re doing wrong

Fwiw she’s shooting a Mathews avail with a single pin Tommy hogg, and an index release

(The high shift also happens at 3d shoots. Eventually she’ll start shooting up into the spine and over the back)

So if any of you have anything I should watch out for it would be greatly appreciated. She likes shooting, but when she starts shooting bad without knowing why, it really takes the fun out of it for her

Take some pictures of her form at the beginning, midpoint, and end of the shoot to see if her form is deteriorating throughout the shoot.

Is tiller tuning still relevant with parallel limb bows? with older bows we used to adjust the tiller on one limb or the other to make the bow pull slightly up or down at full draw. If it is still a thing on the newer bows hers may need to be tweaked, as she gets tired the effect of the bow wanting to pull upward may be affecting her shot. maybe something to consider.

Throw in a small peep sight. When I, @KickinNDishin , or we see folks start to wander, it is almost always related to a slight inconsistency in peep/sight alignment from a tiny bit of head turn or anchor slip. A smaller hole to look through should tighten it up and narrow it down to the above hiccups.

Im speaking from personal experience so take this for what it’s worth.

Sounds to me her face to string angle is changing. She’s possibly tilting her chin down, lowering her anchor point or both. If she doesn’t already do this, have her align the string to just touch the tip of her nose when aiming at full draw. If she is progressively lowering her chin/tilting her face forward, she’ll be able to feel the string pressing in to the tip of her nose more than normal.
