Brew Batch #83 Jake's Juice

I want to see how long I can re-prop this yeast without detriment. OG 1.051+0.001 @67F, from 3 batches ago? Thank you Siebel, on 60bbls this could be $500 per pitch yeast management. Plus, the neighbors are pulling growlers faster than I can entertain bottling! It's amazing how fermentation was full blown within 4 hours. It's also the same strain for my impending Mango Wheat Oktoberfest entry.
