Hey Richard, R3 investors who invested a certain amount (if I remember correctly, it was £500) get absolute priority over any referrers, straight after R1 and R2.
Moreover, @Freetrade_Team has said that R3 investors still will get a significant queue jumps regardless of the amount invested:
Ignoring that queue number for the time being may help. After all, it is still early testing and as you can see (i.e. not related to the queue position but manually selected based on the backgrounds), there are a few areas to improve. You just will be lucky not to experience all the issues other users have gone through and reported recently
