Agreed hematite.
Existing holders who dont wish to increase or reduce their holdings can sell on market for 26.5 or 27c and buy into the SPP at 26c and lock in a small profit. Yes its a very small profit after brokerage but its risk free. So upward pressure on the SP may be getting capped by small sellers undertaking this arbitrage.
Personally, I probably won't sell any shares and will take up 5000 in the SPP.
