Dynamic Re-calculation does not update values on form

Chrome Browser

Problem:
Log shows Dynamically calculated value is changed but it is not replicated in the user form on the screen.

When you change a value of an attribute the dynamic rule is triggered to update another calculated filed.

Eg.
Field 1 - Gross Weight
Field 2 - Net Weight (calculated)

'Executing' loader is displayed and if you tab through to the next field while it's 'Executing' the value of the calculated filed is not populated or changed.

The re-calculation is not broken or anything and the log shows that the rule executed fine and that the value has in fact been changed.
Issue is, this is not replicated on the user form which still shows the old value.

If you don't tab and wait, then the calculated filed is changed on screen.

Consequences:
We have a attribute showing Total Amount to be charged on a card and since this is occurring, the user might charge the wrong amount.

What is expected:
The value of the fled on the form to change (as it does in the log) even if the user tabs onto the next field.

Our processes require a quick data entry and that means tab through the fields. It's not user friendly to wait 3-4 seconds for every 'Executing' message to finish before we move to the next field.

Has anyone had a similar issue.

This will also prevent any subsequent changes to other attributes from being displayed on the screen.
Those subsequent changes to values triggered by rules only appear in the log.

Also just to clarify, the first tab triggers the re-calculation; It's the next tab soon after (while executing) that's causing the issue.

Why the long 2-3 second 'executing' delay message?

The object in question has approx. 150 business rules in total.
They all play a role and execute just fine.
If an attribute is calculated, on average, only 10 rules directly affect its value.

The only issue is the 2-3 second 'executing' delay every time the re-calculation is triggered.
The delay is always there since re-calculation triggers all rules to evaluate and most to execute regardless if dynamic or not.

A object with just a handful of rules is also affected (tested this on object with only 5 rules.).

Rennur

System allows for re-calculation to execute during a re-calculation already taking place.
They don't seem to be in queue and executing one after another.

I haven't heard anything back form support on this as yet, but below is the log & user form.

We all know that the re-calculation is triggered when you enter or change a value and un-focus from a form field ie. tab to the next field.

Normally there is no issues as the rules re-calculate almost instantly.
But if the re-calculation takes longer (eg. 2 sec) due to a larger number of BO rules, the user cannot tab to the next field and define it while the executing sign is on. It breaks the preceding calculation and the field values of that calculation do not populate the web form.

You could argue that there are probably too many rules, you should utilise non-persisted BOs as params more and the user should really wait for the form to re-calculate hence the 'Executing' message popping up.

All arguments aside, there is an inconsistency between the system log and the user form as per pics below.

Log - says the values on the form are defined

Web Form - not defined
