## Instruction

```
This is a code generation task. You are expected to write working code that solves the described problem.

      ## Proposal
Remote-write should try to make up time faster, by putting more weight on the backlog of un-sent samples.

Here, we first compute a coefficient of 0.1 divided by the sharding tick, which is 10 seconds, or 1/100, then apply this to the number of pending samples:
https://github.com/prometheus/prometheus/blob/e8663a4eacd310f403ebf5ce492494652dd69379/storage/remote/queue_manager.go#L830-L834
Effectively we target 100 seconds to clear the backlog.

The point seems to be aluded to here: https://github.com/prometheus/prometheus/issues/6333#issuecomment-555360746
> I believe the weight of the samples pending within the calculation isn't enough, but again this is just my theory.

however the source of this quote is not given.

Personally I find 100 seconds to be very long.  There are a couple of suggestions in #6333 that it should be "a few scrapes" or "`batch_send_deadline` + 1m" (65 seconds by default).

I think I would be ok with 30 seconds. I don't really want to make it configurable since hardly anyone will configure it, but I guess that might be the easiest way to find the "right" value.

</issue>
Focus on implementing the required functionality correctly and efficiently. Treat this as a programming challenge.
