Asking for a lawyer time limit Maryland v. Shatzer (2010)

Here's something I didn't know. If a suspect invokes his right to remain
silent AND his right to have an attorney present during questioning,
police can resume questioning on Day 15. This is when the suspect is not
in custody.

Plus there are utterly bizarre rules when the suspect is in custody. One
is in custody in general population but not in custody in an
interrogation room at the jail or prison, even though the suspect isn't
free to leave. That restarts the clock.

The lawyer advised to log when one invoked right to counsel to remember
when he needs to invoke it again, but it seems safer to invoke it every
single time.

How does anyone remember all this?
