You can calculate Theoretical mechanical advantage[TMA] of pulley system.
- Ideal Mechanical Advantage (IMA)—Calculate the efficiency of all pulleys at 100%
- Theoretical Mechanical Advantage (TMA)—Calculated with pulleys including friction loss
- Actual Mechanical Advantage (AMA)—Data actually measured by measuring machines

Brake &pullyes efficiency reference data
Example
The brake is first pulley of the multiplier part.
Base: 600-5(100-95)-4(100-95)-3(100-95)-2(100-95)-(100-92)=522
Multiplier : 500-4(100-90)-3(100-85)-2(100-90)-(100-92MPD)=387
522%*387%=20.20
total MA 20.20:1
■5:1redirect (2+3):1
all multiplier pulleys 90%
break 50%
200-2*(100-90)-(100-90)+(300-2*(100-90)-(100-90))*(100-50)=305
