Q. Was there an instamine?
A. No. There was a hardfork at block 2200 to make things more suitable to solo mining. From this block forward, the block reward was reduced from 66.66 SPR to 6.66 SPR (diminishing over time as per the supply curve in the OP) and the blocktime was reduced from 10 minutes to 1 minute. The Spread generation speed and total supply thus remain the same, as one tenth of the SPR is being generated ten times as often.
