For barbell lifts, most apps use formulas like Epley, Brzycki, Lander, O’Conner, etc. But for weighted pull-ups/dips, the estimates vary a lot depending on the formula and how much bodyweight you count as moving load.

Example:

• Bodyweight: 91 kg
• Bodyweight coefficient: 0.95
• Moving bodyweight: 86 kg
• Added weight: +40 kg
• Reps: 6

Using total moving load with Epley:

total moving load = (91 * 0.95) + 40 = 126 kg
estimated total 1RM = 126 * (1 + 6/30) = 151 kg
estimated added 1RM = 151 - 86 = +65 kg

But in practice, my actual 1RM was closer to +55-57 kg.

The Kensui weighted pull-up/dip calculator seems to use a more conservative rep-percentage table, where 6 reps is about 89% of 1RM:

estimated total 1RM = total moving load * (100 / 89)
estimated added 1RM = ((86 + 40) * (100 / 89)) - 86
estimated added 1RM ≈ +56 kg

That gives a much closer estimate.

So I’m curious:

• What formula do you use to estimate weighted pull-up/dip 1RMs?
• Do you use Epley, Brzycki, RPE tables, percentage tables, or something else?
• Do you count full bodyweight, partial bodyweight, or just added weight?
• Do you find different formulas work better for pull-ups vs dips?
• What rep range do you trust most for estimating 1RM?

I’m especially interested in what experienced streetlifters actually use for programming, not just what generic gym calculators say.

I’m looking for some good apps! I’ve looked at a couple like strength log etc but they all seem too easy, with the longest workout I saw being less than 30 minutes. Any help is appreciated it!
