hi group, ive been trying out and experimenting different modes of progression, specifically, last set to failure and additional set, because im plateuing on pull ups. im currently at 6 but i just got 7 today

in my last last workout, my numbers on Pull-ups are 6,6,7. in my last workout, i added another 6, therefore, i had 6,6,7,6.

today, i aim for 7,7,7 as per recommendation on the book which is additional set. my numbers are 7,7, and 6, just one rep short. i like doing pull ups, so adding an additional set is a treat for me. howeever, i dont know if i should add another set because i failed to do 7,7,7

what should i aim in next session? should i aim for 3x7 before going 4x7, or can i do 7,7,6,7 straight, away?

i do pull ups with good form and my aim is 10 pullups with good form before progressing. thank you for help.
