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.
