I'm not too sure about my vertical jump at the moment but I will say that it's nothing spectacular, probably pretty average as I am not a serious or competitive basketballer (compared to other people I know who play at a much higher level than me e.g. "Representative" basketball playing for different region clubs or a higher level of highschool basketball) and only playing friendly games with friends and also once a week on Friday nights for a "club" competition.
If you have some chalk/ink, dab a little on your fingers. Next stand next to a wall sideways and extend your arm(the one towards the wall) as much as you can. Mark the position with the chalk/ink. Next after some light warmup/skips/sprint whatever, stand next to he wall sideways again and jump up as high as you can explosively and quickly mark the point on the wall with your extended arm.
Next measure he distance between the 2 marks and voila you have your vertical jump measured.
I tried out the hopping thing a few times (does it matter how far I jump? Or as long as I get on the other side of the line, it will be counted as a hop?) and I counted somewhere between 20-25 forward hops so I guess I'm not that efficient on my feet? lol.
No it doesnt matter how far forward you jump, as long as it is rhythmic and you should be doing it on your toes. 20-25 is not bad at all friend. First time i tried it, it took me 16 seconds to do the 30 forward hops. Practice this drill a 2-3 times week for 3 sets and you should see pretty rapid improvements. You should aslo find that your 3rd set is the best. I would take 1-2 min rest b/w each set. It's a basic movement efficiency drill and once you will be able to do the require number of repetitions, you WILL feel very light on your feet(ie walking, running, climbing stairs etc will feel much more effortless)
Can I ask, what do you mean by a "base strength"? Would the amount one could squat be considered one's "base strength"? And what do you think about implementing Power Cleans into my workout to build power?
A good base strength is a 1.5xBW squat for few reps(2-3) at least. Depth jumps and drop jumps are effective only then as depth jumps make your body take 6xbodyweight force during each landing and drop jumps are even more than that. Such huge amounts of force will cause tendon damage if your try them now.
However you can still do basic drills. Those line hops are one of them.
It seems to me as if you are a raw beginner right now. Is that a good thing you may ask. I'd say hell yes

Best way for you to increase your jump is to increase your squat and keep practicing the vertical jump. If you want to know how much you should be able to squat to jump a certain height or how much you should be able to jump if you squat so much, go to the following link:
