No updates to Google for very small nominal daily budgets

When an order is deployed with very small budget say $0.2 or $0.4, there are no proper updates being sent to Google in case of US Taxonomy.

Steps/Observation/Notes:

Deployed the new bidmgr build #556 to verify aml-3310.

1) Deployed a new order with budget $0.2 and ran abu
SELECT * FROM `st-tracker`.admaxSearchEngineAccountActualDailyBudgets WHERE searchEngineAccountID IN (3938,3939)
searchEngineAccountID date budget actualSEBudget budgetStatus
3938 2015-01-14 0.00322581 0.01 Paused
3938 2015-01-15 0.00645161 0.01 Active
3939 2015-01-14 0.00322581 0.01 Paused
3939 2015-01-15 0.00645161 0.01 Active

I noticed that a budget increment of 0.006-0.003=$0.003 has sent updates to Google.
Earlier it was such that only a budget increment of >=0.01 was sent to Google.
Is this something that you have changed?
And if so what is the minimum increment value that will send updates to Google or is it expected to send updates whenever the status shifts from ‘Paused’ to ‘Active’?

Ross: Yes, a change in budget status will now result in a change at the search engine. This resulted from our discussion about AML-3310 last week and was noted in my comment in Jira.

2) a) Deployed another order with budget $0.4 and ran abu
SELECT * FROM `st-tracker`.admaxSearchEngineAccountActualDailyBudgets WHERE searchEngineAccountID IN (3940,3941)
searchEngineAccountID date budget actualSEBudget budgetStatus

In the above example there is only one update sent to Google though the budgets for both the campaigns are the same.

Ross: As we have discussed, "random updates" occur in about 10% of budget changes. If you run this again it may result in 0, 1 or 2 updates

b) Ran abu for the next day t+1
SELECT * FROM `st-tracker`.admaxSearchEngineAccountActualDailyBudgets WHERE searchEngineAccountID IN (3940,3941)

Though there is a change in budget, there are no updates sent to Google.
No updates in Adwords

Ross: The change in the `budget` column is used to determine whether to send the budget to the SE. If a change is indicated, the value sent is the one in the `actualSEBudget` column. This scenario is why we added the "random updates" so that very small budget changes would eventually get sent to the SE

There is only one update sent to Google though there is a change in budget

Ross: Same as 2a
