Currently, in a random split branch in workflow, HubSpot enforces an equal distribution. It’s not possible to adjust the percentage: ![karstenkoehler_0-1712558903176.png](https://d2qpr2jzcazej7.cloudfront.net/original/3X/2/e/2e2ec4ec98f9eb6b9d9ddfb579e1a8e88937b64a.png) It would be great if it was possible to adjust these percentages, the same way that list splits are allowing for custom / flexible splits: ![karstenkoehler_0-1712559178996.png](https://d2qpr2jzcazej7.cloudfront.net/original/2X/5/5e8ee5214349f43ef72d06371ec133735de9dd2d.png) Thank you for considering this request! ---

This is much needed, when we run AB tests we want to also be able to rank against a 10% control group. ---

This will solve a lot of pain in lot of places! also, if hubspot can allow by teams that would great an extra added feature! ---

I assumed we could adjust the percentages as I’ve used this w/ an equal split w/ a few workflows. Then I had one where I wanted to adjust the percentages manually and learned this wasn’t possible. While not perfect and it lacks some granularity, I created a random distribution branch in my workflow with 10 branches. Branches 1, 2, 3 and 4 held the main work flow. I directed branch 5,6 to branch 1 thus giving this a 30% chance of hitting branch 1. Branch 7,8 pointed to 2. And 9, 10 pointed to 3 which gave me the distribution i was looking for: 30%, 30%, 30% and 10%. Ideal? No, but it works. ---

Nice workaround @TeddyRuxpin ---

This is necessary ---

This seems necessary and logical seeing as you can already use preset, equal percentage splits. ---

100%!!! Generally A/B testing is done with a small portion of customers (ie 10%) to start off with. To get that type of split, we have to separate each email into x10 versions to get that type of split. And that’s for one email in a workflow. What if we have 2+ emails in a workflow??.. the number of branches exponentially grows and becomes unusable! PLEASE can we get customisable random distribution options! Pleeeeease!!! (and thank you). ---

I fully support this idea! 💪 In our lead assignment process, we need **flexible weighted splits** to ensure a fair assignment of new leads. Currently, we’re forced to use custom code for a **weighted lead rotation** – which works, but adds unnecessary complexity and makes maintenance harder. A **native feature for weighted random splits** (including custom percentages) would make these workflows far more reliable, scalable, and accessible for teams who manage lead assignment.
