I’m curious what the effect of improving Trial Accuracy above 100% is. The description doesn’t say anything about it.
Strange, I somehow missed this post when it was first made. I’ll gladly explain. 
100% means 100% of the normal amount of trial accuracy, in the sense of 100% of 6 is 6.
150% means trials are 50% more accurate. In real terms this means that the bars that you get in the results will deviate 50% less away from the “true value”.
Higher accuracy means that results will be more consistent and will tend towards the true cure rating of a product. Low accuracy means that there will be more deviation which can be good if you are looking to disqualify results and overstate your product’s effectiveness.
