How I should measure my progress[?]
The only way you should measure and/or gauge your progress is by tracking and comparing against yourself. To be clear, the best metric is your own individual progress. What did you lift yesterday, last week, last month, or last year? How do you compare against that? That's the best measure.
Why? Ultimately, there is no way to compare two individuals in their journey through fitness. People don't have the same height, weight, hormone levels, stress levels, nutrition, leverages, training plans, technique, support, money, or time. The list could go on. If I were to look at every Gymshark 16-year-old-upcoming-powerlifting-star who out lifts me on every lift and ask myself why I'm not that good, I'd go insane.
With that said -- I get wanting to know how you stand. I'm in powerlifting. That's literally the sport. The best way to make sure you're not setting unrealistic goals is by keeping your strength expectations relative. This article from StrongerByScience talks about objective strength standards and also links to a very popular Strength Standards Table. Specifically, Squat, Bench Press, and Deadlift in kg. Remember, when you're looking at these tables you should be using your 1RM for the lift. If you've done a 3RM you'd want to convert it to an e1RM using something like this calculator. For example, if you can Squat 60 kg for 3 reps, and you think you still could've done 3 more reps to absolute failure you'd enter:
View your Estimated 1 Rep Max: 72.5
Based on the website's definitions, if we accept them, then we'd be saying that we are to reach the intermediate level, for a given body-weight, within a couple of years of training that specific lift, with intention, nutrition, and support.
September 2021 you hit 60/60/80 kg on SBD but with +20-30 kg on squat and deadlift with form breakdown. I don't advocate for bad form and form breakdown is not good for training or long-term health, but unless it's severe, I'd count it. A 90 kg squat, 60 kg bench, 110 kg deadlift at 61 kg BW puts you around ~Intermediate/Novice/Intermediate. If September was a month, that makes February six months, and I'd say you're making excellent progress.
** Quick RPE breakdown: If you did a rep and you absolutely could not have done any more reps or weight, that's a 10. Could've done more weight but not another rep? 9.5. Another rep? 9. Two reps? 8. Three reps? 7. Four reps? Your training weight isn't heavy enough.
