Contrary to popular belief, multiple chains ARE allowed in all sub-steps of the damage step EXCEPT the "During Damage Calculation" sub-step.
Yesterday I chatted with Franklin Debrito who was the HJ of the SJC in CA last weekend. Franklin talked with KDE R&D and the subject matter was one of the very questions he asked them about. My statement above is based on that conversation with Franklin.
Below is a post I formulated in respose to another on Pojo that might help explain the reasons for the misconception.

While what you stated here is the widely accepted interprutation of Curtis's damage step details post, I'm not absolutely certain it's accurate...yet. I'm trying to get some clarification on the matter.
Please don't take what I'm about to write below as anything but thinking out loud for the time being but....
When Curtis released the updated damage step details, there were a couple of points that left room (at least in my mind) for clarification.
The main point I'd like cleared up, if anyone has any further information, concerns multiple chains in any other sub-step other than during damage calculation.
Most players and judges are assuming that because multiple chains are specifically mentioned during sub-step 3 Start of the Damage Step, that this is the only sub-step that multiple chains are allowed in, however, the wording in that paragraph doesn't specifically state that, instead it reads...
Effects that increase, decrease, halve, or double the ATK and/or DEF of a monster are typically activated at this time. You are allowed to have multiple Chains for the use of activating these types of effects. If you activate “Rush Recklessly” and it is negated by your opponent’s “Magic Jammer”, you can start another Chain by activating “Rising Energy”, etc.
Notice the paragraph doesn't say, "You are allowed to have multiple Chains for the use of activating these type of effects...in this sub-step only" Instead, it just refers to the type of effects that can be used in multiple chains. Those same type of effects are mentioned in sub-step 1 and sub-step 2.
Am I reading too much into this? I don't know, I'm not attempting to read anything into it, rather, I'm trying to find out if many are reading too much into it by assuming that sub-step 3 is the only sub-step that allows multiple chains when nothing Curtis wrote implys this.
The only thing that Curtis wrote that is specific to the number of chains allowed or disallowed in any sub-step is in the "During Damage Calculation" sub-step where he specifically states, "We only get one Chain with which to activate effects that are activated "during damage calculation" Why would this be specifically stated in this sub-step description if it were applicable in other sub-steps as well?
