Joe Root has rejected suggestions England could set another ODI record against India today.
They start their three-match series at Trent Bridge after a 2-1 defeat in the T20 matches.
England set a new ODI record of 481 for six when they beat Australia in Nottingham last month.
Another big score is expected but Root has dismissed suggestions England are ready to break their own marker.
He said: "It's dangerous to think too far ahead. One thing we have been good at is assessing things early on and planning an innings.
"It might be the case, it might not, but ultimately it's about winning the series and coming out of what has been an impressive white ball summer."
England are the number one ranked ODI team in the world and whitewashed Australia 5-0 in their most recent series.
India sit second in the rankings and Root expects a difficult tussle following the T20 series defeat.
He added: "India have been a really strong team in this format for a long time. Ultimately it's good marker to see where we're at.
"It's an important series, we have played some really strong cricket in one day format and India are one of the best in the world."
Meanwhile, India vice-captain Rohit Sharma insists their one-day international tour will be crucial to their World Cup preparations.
England and Wales host the World Cup next year with Sharma eager to get some early practice in.
He said: "It is very important, since the World Cup is going to be played in this part of the world.
"In terms of preparation it's very important, in terms of our combinations and what our targets are going to be.
"We have seen England against Australia and they were really high scoring games, it's gong to be crucial to see where we are as a team.
"In the last year or so we have played some good cricket, in and out of India, this tour brings another challenge for us."
