Hi Justin,

Thank you for contacting Amplitude Support. Happy to help!

Please allow me to check with my team regarding your experiment implementation. I will get back to you shortly.

Thank you for your patience and understanding!

Hi Justin,

Thank you for your patience!

I consulted my team about your use case. You are correct in your understanding. If you use the same Bucketing Salt for each of the flags and keep the segments and rollout numbers the same, the same users should indeed receive all 3 flags.

This is due to Amplitude Experiment's consistent bucketing, which is based on the user, bucketing key, bucketing salt, allocation percentage, and variant weights. Given the same inputs, the output remains constant.

However, there are a few things to be aware of:

1. Changing the bucketing salt can cause users to switch between variants in your experiment. Therefore, it's recommended not to change the bucketing salt unless necessary.
2. If a user moves from one segment to another, they may be assigned to a different variant. This is known as 'Variant jumping'. To prevent this, you can enable a feature called 'Sticky bucketing', which ensures that a user will be assigned the same variant, even if they move between different segments.
3. Lastly, while using the same bucketing salt value for all experiments/flags will ensure that users receive the same variant, it's recommended to create a test experiment in a test project to observe the behavior before implementing it in production.
I hope this helps! Let me know if you have any other questions.

Best regards,
Thao
