Welcome to Phillip!
My personal opinion is that 32C is a bare minimum and sometimes a tort will sit under the lamp for long periods just to keep adequately warm.
If you raise the temperature at the hotspot a few degrees no harm will result (in my experience) but there must be space for the tortoise to move away from the heat.
This might result in more activity.
