You have an extra month now? If so that’s a good thing I think.
What do you mean " without the extra stressor" ?
Likely you are extremely capable which is an excellent thing but maybe you need to be a bit more progressive with your explosive throws and build into the design of your training a more reasonable progression now that you did this today and had to back off.
I would start with one set of forward explosive throws 4x ( what weight are you using for your med ball?)
followed by 4x backward throws
then I would take a break / shake your legs / stretch
do one more set of each
another break as per above
then I would try single hop throw 3x
This is what I would start with the next time you do this workout
sets of 10 for anyone imo is extremely high
Likely you will feel a bit wanting for more after my suggestion ( if you take the advice which you are not obligated to do) but I have never seen someone do that amount you suggested / not saying it can not be done but if you could feel quality deteriorating I bet it was visible well before that.
