I missed some records during import of the delegation files:
2001:3bc0::    29        allocated to LIR
2001:3bc8::    29        reserved
2001:3bd0::    28        reserved
2001:3be0::    27        reserved
2001:3c00::    29        allocated to LIR (this record was missing in my import)
2001:3c08::    29        reserved
2001:3c10::    28        reserved
2001:3c20::    27        reserved

RIPE NCC explained that for every /29 they reserve a /26, so this matches the table above.
However if we will go for nibble boundary, we will have a lot of reserved space left as the next step after /28 will be the /24.

Yes, you are completely right, I meant 2001:3c00::/29. However, we still have this "hole." Is there a technical reason for this?
