I’m trying to workout this problem but I think the solution is not calculating the PC stations correctly, or am I missing something?

I calculate all the same curve data for all three PIs, however at PI1, the PC1 station is just (PC - T). Why isn’t it the same for the other curves?

For example, for curve 2 the PC2 Station should be 33+07.61 (PI2 - T2), but instead the solution gives 33+03.35… am I missing something? Or is the solution wrong?
