Simulating Abanadoned flows in JMeter

A user wanted to simulate abandoned flows in JMeter - e.g.a  multi step checkout scenario where some number of users drop off at every step

This was my suggestion

+Sampler1
+ThroughPutController (90 , percent executions , uncheck per user = 10% abandon)
++Sampler2
++ThroughPutController (80 , percent executions , uncheck per user = 20% more abandon at this step)
+++Sampler3
