For me, jelqing was always about the Uli squeeze. I can only jelq with dry skin, dry fingers and a good grip, slightly maneuvering the fingers towards the lowest base possible while being super horny and determined and also ocasionally trapping and squeezing the hardest erection at the highest erection level possible while pushing it a little forward (this also has a name, “supra slammers” iirc).
Jelqing with lube like in the described videos that used to be around, going towards the head and then placing the other hand at the base and repeating the motion, that never worked for me and also gave me skin issues like pimples or dark spots here and there, plus discoloration gets worse for me with this motion somehow.
