How upright can an old style Marathon be RF'ing?

My 2 year 10 month old child wants to rear-face again and she is not longer doing dangerous things to her baby sister who is RF'ing next to her so I want to put her back Rf'ing but space is an issue front-back.

Your Marathon can be as upright as 30 degrees. If you have a smartphone, you can download a level app that can make measuring easier. Just be sure you're parked on a level surface.

My understanding was it could RF safely up to 30 degrees. Hopefully someone else will come along to confirm or correct me. )

Thank you! Do you know the name of the app?

On my droid I used one called bubble. Some people use clinometer.
