Crystal Capacitance: Does it matter on a programming board


i'm making board program smd atmega328p's.  programming board has tqfp32 socket mounted on it.  seen in attached photo, traces crystal go inch or so, , through small dp3t switch.  @ first concerned correct capacitance crystal caps, if it's not perfect, mean?  --that ppm might off little?  if so, makes no difference, chip in programmer long enough have boot loader installed , tested.
the reason dp3t switch can program smd chip either 8mhz external, 16mhz external, or internal clock, , test newly programmed chip whichever crystal it's set switching crystal switch.  i'm guess there's more capacitance in traces, reading online seems impossible calculate such things math only. 
am correct if use normal 22pf caps should fine application it's in?

ps.  crystal pins on bottom center of socket , traces go on right edge, dp3t switch seen silkscreen.

thanks.

afaik 12pf parallel crystal needed make them resonate @ right frequency.
2*22pf in series (seen crystal) 11pf, plus bit of board/pin capacitance...

if longer tracks/switches used, drop fixed cap values 15pf.
i think values can off quite bit before crystal stops oscillating.
