I think that calculator uses wrong BTC/GRC: that's the change for the old GRC, each of which converts to 10 research GRCs, so the BTC/GRC change should be divided by ten.
Not necessarily - it reflects the current GRC/BTC price. We are optimistic the price will not crash by 10* when we switch tickers.
Currently you can convert a classic GRC, which is about 4000 satoshi, to 10 research GRC, so a research GRC is exchanged at 400 satoshi, and this is the only way you can buy a research GRC with BTC.
I stand by my statement regardless. Our price is going to be somewhere between where it is now and the reverse split amount.
The market is a free market, so no one knows right now what the result of the calculation will be. (So making a change to the calculator would not be prudent).
