I'm trying to figure out where I screwed up.
R1: 3Ths for $10000 = $3.33/gh 300 shares 10Gh each $33.33/share
R2: 10Ths for $10000 = $1/gh $5000 RIF + $5000 raises by selling 150 shares at $33.33 each 13000GHs/450shares = 28Gh/share $1.17/gh
Hmmm...
R2 revised "The Complicated Way": $5k from R1 RIF money and $5k from 150 300 new shares at $33 $16 in R2 money each round gets 5Ths to split so R1 members now have 26Ghs/share and R2 members now have 33Ghs 16Ghs/share.
Double Hmmm...
I think I need to go back to 10th grade to understand but I think there's a way you can structure the number of new shares and the cost of each new share to balance everything out.
EDIT:
R2 Revise again "Te easy way": sell 192 shares at $26 each and now everyone has 26GHs.
Done!!! Take that Mr. 10 grade math teacher guy!!! LOL
Good job

You passed "earlier" obstacle. There is exactly only 1 number of shares per situation, where you can balance single round to make it at least the same as other ppl will offer. Too many things should match. And it should run with organizer with good math.
Now compare it with option #1 + same reinvestment. Add "5Ths for 5000$" machine in market (same $/gh rate).
..
Exactly the same

Both rounds have 26 GHs per share. But now you can open rounds with any ammount of shares and any hardware. And you don't need math skills to balance everything out each time.
Back to option #3. What happens if hardware broke? Or became inefficient to mine (high W/GH) and can only be sold under market $/GHs rate. How to balance everything out? Somebody should pay for it.. New shareholders (overpriced shares) or old shareholders (steal from RIF) or some poor guy on eBay, who has bad knowledge of btc hardware or it should go from organizer wallet.. Which path will you go?
People in later rounds will buy shares, that include obsolete gear. With absolutely no better sides compared to other GBs or option #1 + reinvestment.
