When can subs come in?

[Nevadaref]

Sharpshooternes,
I believe that you are unnecessarily confusing yourself with terminology.
While there is such a category as a player technical foul, there is no such thing as a personal technical foul.
What would help you is to organize the foul categories as follows: the two main categories which are mutually exclusive are personal and technical.
Now there are several modifiers such as intentional, flagrant, double, false double, simultaneous, etc.

Now the words personal and technical always go at the end with the modifiers before them. Hence, we have the four following types of fouls whereas in your original question you listed three:
Intentional personal
Intentional technical (such as deliberate contact during a dead ball)
Flagrant personal
Flagrant technical

If you consult rule 3-3-1c, you will see that the restrictions on entering substitutes are only for personal fouls.

So now give me your answers to the timing of substitution entries for each of those four types of fouls. (Before both, before last, after both)
