The Reds registered a Super Over inter-insular win on Friday night as the two islands played their first official ICC international against each other, before the visitors claimed 41 and 76-run successes on Saturday.
The series acted as a focal point for preparations before the continental World Cup final in Guernsey later this month, but Perchard believes Jersey must start afresh.
‘We’ll be full of confidence [going into the ICC tournament], but this weekend’s cricket will mean nothing,’ he said.
‘We play Guernsey in two weeks’ time on this field [the KGV] and we’ve got to put in another good performance otherwise we’ll be struggling in the tournament.
‘Friday night was a very interesting game, we certainly weren’t at our best, so to get over the line in those circumstances [a super over], credit to the boys.
‘Elliot Miles did particularly well coming back from having been hit for two 6s off the first two balls in the super over was a top effort and then for Jonty [Jenner] to go out and play with the confidence he did there was really special.
‘Today [Saturday] we really fired, I thought we were fantastic with the bat in both games and we backed it up with some very good bowling and some really good fielding as well.
‘As a team we’ve been building up over the last few years, we’ve had an unchanged group of players and that certainly stands in our favour.’
Guernsey captain Josh Butler said: ‘Friday was a big positive for us compared to last year – a game we not necessarily should have won, but we could have got over the line there.
‘Today [Saturday] was Jersey showing they are the next step up in terms of strength in depth and things like that.
‘Everyone they called upon came on and did their job, I don’t think we quite did that. We used all 14 across the day, which is a positive for us in the sense that we get to see how people are playing, but we went down a couple of levels from yesterday and Jersey went up a couple of levels which is why we took a battering today.’
Looking ahead to the Europe Final, Butler said: ‘The Dutch will be tough, they are bringing a strong side.
‘We feel Jersey are going to be the best team in the tournament, they are well organised, they are well drilled, and they are going to be just as strong, if not stronger, with the players they are bringing over.’
