taping into existing chain of outlets

scenario #1
if there is a direct linear chain of 5 residential outlet boxes is it acceptable to tap into one of the boxes in order to run another leg with another 1 or 2 duplex receptacles? if so is it acceptable to take off from the unused terminal screws of the outlet rather than have to redo the existing pigtails?

scenario #2
if there is no convenient existing outlet box to tap into is it acceptable to tap into the wire midway, add a splice/junction box and continue from there with the second leg?
note- the only problem with this is that there is not enough slack in the wire so an additional foot of wire will be required to be spliced to extend to the existing run, meaning another splice box next to the junction box.

thanks for the advice

Scenario #1-Yes

Scenario #2- Yes providing the new j-boxes are accessible.

What Jack says, and let me add to #1: depending on what you will be running off these receptacles, is your breaker big enough?

Re: taping into existing chain of outlets

Ditto Jack and DJ.

Also up to 13 receptacles or lights are allowed on a 20A circuit. Ten on a 15A.

Thanks

Is the 13 receptacle for a 20a circuit a hard line rule? Meaning one duplex outlet will count as two receptacles?
The wiring in question will be for a basement workshop and i was going to use 4" sq boxes with two duplex outlets in each ( 2duplex=4 total outlets in each box)
A lot of the devices will be low load items, lighting,chargers etc.

A duplex receptacle is one receptacle.
