10 second count on small court?

[OYC2013]

What are the general rules when officiating a youth game on a very small court when the backcourt line is actually a point before the marked midcourt line as far as 10 second rule and backcourt violation? Do you use the court's true midline as your 10 second count point and then once the player dribbling the ball crosses the mid court line, the backcourt line becomes that first line that was crossed, which effectively allows for a bigger front court?
A little hard to explain, but anyone who has reffed on a small youth-sized court should know what I mean.
