In a smart campaign flow step, we are doing some testing and it raised a question as to how Random function works in choice steps. I've laid out two potential RANDOM methodologies and 2 potential scenarios. I'm trying to figure out which is the correct methodology that Marketo uses.
Method A: Each subsequent random step pulls that percentage from the starting pool of leads;
Method B: Each subsequent random step pulls that percentage from the remaining leads;
Scenario 1 is to send 4 versions of an email equally split between each group 25% each to 1000 qualifying leads.
Scenario 1 Method A:
Send Email Step
- Choice 1: Random = 25 (expected result = send to 250)
- Choice 2: Random = 25 (expected result = send to 250)
- Choice 3: Random = 25 (expected result = send to 250)
- Default: (expected result = send to 250)
Scenario 1 Method B:
Send Email Step
- Choice 1: Random = 25 (expected result = send to 250)
- Choice 2: Random = 33 (expected result = send to 248)
- Choice 3: Random = 50 (expected result = send to 251)
- Default: (expected result = send to 251)
Scenario 2 is to send a Chinese and Japanese email to those with that language preference, then do a 50/50 test with the remaining, still a total of 1000 qualifying.
Scenario 2 Method A:
Send Email Step
- Choice 1: Language = Chinese (expected result = send to 150)
- Choice 2: Language = Japanese (expected result = send to 150)
- Choice 3: Random = 50 (expected result = send to 500)
- Default: (expected result = send to 200)
Scenario 2 Method B:
Send Email Step
- Choice 1: Langugage = Chinese (expected result = send to 150)
- Choice 2: Langugage = Japanese (expected result = send to 150)
- Choice 3: Random = 50 (expected result = send to 350)
- Default: (expected result = send to 350)
