A Stupid Question

[Waldszenen]

I looked at the Rach 2 score for the first time today, the first movement. Following the opening eight (or however many) famous chords, the piano plays those streaming arpeggio notes right before the strings come in with the main melody.

My question is; those streaming arpeggios, I noticed, were written entirely in quavers, but as I counted, there were far too many quavers to fit into the bar - that is, there were too many of them and they didn't fit into the beats. How are they meant to be played?

Ugh, a picture is much easier to understand than that load of crap I just typed:

In the beat, couldn't be else.

Some composers don't always indicate tuplets (Liszt is another one).

9 + 8, considering the accents. Not 4-5-4-4 and definitely not 4-5-3-5, at least in my opinion.
