Due to a problem obtaining data from blockchain info, my script has been assessing DeepBit round length data from two days early. The correct payment to date should be + 4.171% greater than expected. This means a bonus of 0.00278145 btc per bond will be paid at the next coupon.

Note: MEI.DEEPBIT.A was not affected by this error.
Below is the actual data for this bond so far:
