Try it online! Explanation: In Retina, a substitution only makes sense if it's long enough l for the number n of repetitions. The substitution saves n(l-1) bytes in the compressed text but costs l+3 bytes in the replacement stages. This gives the minimum length required to be useful as follows:

• 2 repetitions: length > 5
• 3 repetitions: length > 3
• 4 repetitions: length > 3
• 5 repetitions: length > 2
• 6+ repetitions: length > 1

Edit: As @Arnauld pointed out, you can count repetitions from the substitution entries as well. This means that although there were only 5 repetitions of space+s in my previous encoded text, there are also 3 repetitions in the substitutions, thus allowing me to save 3 bytes overall. (@Arnauld himself had only spotted 2 of the 3 repetitions.)

Note: There's lots of unprintables in the following code so please avert your eyes if you're sensitive to such things! :D
