Alstare Ducati's Carlos Checa
was unable to replicate his qualifying form as the Spanish rider twice finished behind team-mate Ayrton Badovini at Silverstone in 10th and 13th positions.
World Superbike star Checa started on the front row in second place but struggled to find the limit of the 1199R Panigale in the damp in the first race and lost out in race two due to a 'lack of power'.
It was a disappointing conclusion to the weekend after a promising performance during qualifying, with Checa pointing to a satisfactory dry setting as the main positive from round nine of the championship.
“The two races were quite similar. When it started to rain in race one I found it hard to immediately understand the limits; I slowed too much in that moment and then, once I'd got back into my rhythm, I'd lost too much time and was unable to reach those ahead of me,” he said.
“In the dry I was just about able to stick with the others this wasn't possible in the wet. In the second race it didn't rain heavily until the later stages.
“There were points in which my bike ran quite smoothly and others in which I could feel the lack of power.
“But in those mixed conditions I made an evaluation and decided that there was no point taking risks for the little that I could have gained,” added Checa.
“Speaking in general about the whole weekend, the positive thing is that we have found a good setting in the dry, working well as far as the chassis and suspension is concerned and so I'm pleased from that point of view.”
Checa's team-mate Badovini twice finished in eighth place at Silverstone.
