Can we include premium information in the same event instead of emiting two events? Coz in second event only extra information is actualPremium which can be combined with GasBalanceDeducted event.

That way we won't need to emit balToDeduct coz that can be calculated using costIncludingPremium-actualPremium

[livingrockrises]

can add actualPremium in the GasBalanceDeducted event as 4th argument.

That way we won't need to emit balToDeduct coz that can be calculated using costIncludingPremium-actualPremium

This balToDeduct we are not emitting currently also. but yes can be calculated.

I will make changes in the event in different PR. because any change in contract I need to show to auditors later as diffs. This is meant for accounting test cases so can you please approve and merge it
