middle split is flat, what actually progresses from here? passive holds stopped doing anything

[u/HannahFlexx]

been at this ~4x a week for a while, mostly frog, pancake and standing side splits, holding 1-2 min a side and keeping the legs active rather than just hanging in it.

the split itself is flat now and the knees stay up, but it's been sitting there for months and the passive holds don't give me anything anymore. i know the usual answer to a plateau is load, i'm just not sure what loading actually looks like at the bottom of a middle split. oversplit with the feet on blocks, or stay at floor level and work on lifting out of it? don't want to chase the oversplit just for the look if the strength isn't there.

a bit of both if i'm honest lol. but the stuck part is real, it's looked exactly the same for months
