Make Tees data look very gappy? Why?

However,

• THAMES AT CHAPMAN BUOY (62.5KMS BELOW LONDON BRIDGE)

seems to have the same gaps as Tees. Why?

But other data doesn't have the same gaps:

• THAMES AT MUCKING (53.2KMS BELOW LONDON BRIDGE)
• THAMES AT OVENS BUOY (47.7KMS BELOW LONDON BRIDGE)
• THAMES AT ERITH (26.6KMS BELOW LONDON BRIDGE)
