on the website robot skills challenge manual found here:https://content.vexrobotics.com/docs/vrc-starstruck/VRC-2016-17-Starstruck-Game-Manual-081616.pdf
on the VRC HUB version of the robot skills challenge manual
Note that there is a difference between the two manuals. As on the website version it states you can only load onto the alliance station alliance starting tile and on the VRC HUB version it states you can load onto any of the two starting tiles.
according to https://vexforum.com/t/a-few-question-about-ultrasonic-sensor/16987/1
it is ruled that the same rule apply to skills challenge which is you can only load onto the alliance station alliance starting tile.
Also i think it would be more clear to understand if it is rewritten as skills starting tile since there is only one legal starting tile to start on each side.
