Janacek- Pedal markings

[l m a o]

 Hi

in Janacek's 'on the overgrown path'- there are two kinds of pedal marking. He is using the regular Ped, but sometimes he is writing 'P'.
What is this pedal sign?

you can check it here

In my edition (Supraphon, Prague) there are only P markings, as far as I can see.

There is no difference.

In my edition (Peters' Urtext) also only "P".   But pedalling Janacek is apparently some kind of thing.  He was more of a folk-music-type-of-man, not very into virtuoso technical piano playing.  He wrote more with a "cimbalom"-sound in mind than with a piano-sound.   So, maybe there is someone here on this forum that can confirm that cimbalom or another Czech' folk instrument has a more specific technique of pedalling (with more nuance or something else) but I tend to think that that copy on IMSLP is just one with some "incoherence".  A quote out of my score "Any technique which contributes to the ideal of an approximation to the sound of the cymbalo is stylistically preferable to an attempt at a traditional piano interpretation..."  So you can use these pedal markings as merely indications.  And one nice piece of advice of Leos Janacek himself : Every note should be played "as if dipped in blood" and every piece should consist not only of "roses" but also of "thorns".

Kindly.
