Really hard to say without comparing to a known good board. The HRS is only wood and glass (no hi density foam layer) but the 0.5mm ish wood is equivalent to a 3mm PVC layer (5-6x more dense) as far as impact strength goes. However, its arguably not as strong as the further apart the laminates are, the stronger the board.
Thus, being thumped = no more likely to cause damage.
Flexing due to hard riding = possibly more likely to be damaged than 'normal' construction.
Compare the deflection to a new board the only way to know I reckon. Or..... it wasn't one of the ones from the fire sale was it....?
If its not from the fire, been ridden in a 'normal' manner, and not in stinking hot car or on a plane, and the softness is
even all over I'd be most likely to assume its ok.
