Some more data we must include the TSAGI stuff for balance ... though I think its a bit skewed to the slow side ... differrent time and place... got to make the local product look good perhaps



And another that looks good with all sorts of detail but no idea on its provenance so caution on its use. Looks like some engineers calculations and extrapolations rather than actual test data ... just another of the countless snippets on my HD
