Go to Post The robot competition is the most obvious, visible, and distilled-media-friendly part of the picture... We shouldn't be surprised that it's all that gets into the news coverage, when that coverage is managed by someone who isn't already well versed in what FIRST is trying to do. - Alan Anderson [more]

I am aware I am beating a dead horse here , but using unmodified Sirwin's code I am getting ~12 seconds with an i7-6560U (2.2GHz) and 8gb of RAM, memory usage is low so we can eliminate that as a factor. The bottleneck is (unsurprisingly) CPU clock cycle speed.

I'm using firstapiR v2.0.0
