Question on L2 to L1 gas limit.

Hi.

What is the safe gas limit value that can be used when relaying messages from L2 to L1.

I assume that the  min gas limit will be used on the L1 side. 

For example, in my case, I am settiing 1.5M as the min gas limit. will this sufficient all the times irrespective of the peak time.

Please advice
