Starter has higher peak when fed at a lower ratio

When I feed my starter at a 1:1:1 (starter:flour:water) ratio, it peaks at around triple its original volume.

When I feed it at higher ratios, e.g. 1:5:5, it peaks closer to double the original volume.

Any idea why that would be the case?

How long does it take to peak in these conditions?

It's possible longer time lets more acid accumulate and at some point gluten starts degrading, so it can't hold up any more.
