+1, as mentioned above. You've got already good advice.
You used the same caul as for the other 62“ long bow. As this one is shorter the effect of too much deflex or too low reflex is much more obvious.
You should make another caul, so that your tips are laying in front of the handle not behind. Better and much easier is to work with two cauls, one for each limb. Gives much better control and time. Steam the limbs, then heat treat on caul if you like.
I‘m not sure how your form looks really, as the camera shows it in an angle. Make sure that the reflex curve have an increasing tendency.
Another tip: Note the reflex after the steaming/heat treating, I call it initial reflex. Compare the number with the remaining reflex after tillereing and then after shooting in, I call it netto reflex.
Of course the aim is to keep the difference as low as possible. Watch where you lost the reflex.
This is just my opinion, no harm, Just want to help!
