Glamorgan captain Jim Allenby says the fixture schedule facing his side is "not ideal".
The Welsh county play the first of their two One-Day Cup matches in two days, against Middlesex on Saturday, just hours after their T20 Blast win over Gloucestershire.
But Allenby thinks winning with eight overs to spare to reach the quarter-finals could be of benefit.
"Finishing so quick tonight [Friday] has helped us," said Allenby.
"It's not ideal but it's part of the job."
Glamorgan clinched their place in the last eight of the T20 Blast in convincing manner limiting Gloucestershire to 108-9 as they lost three wickets to run outs.
Tom Smith (2-24) reduced Glamorgan to 29-2 with two wickets in three balls, but Rudolph (44no) and Goodwin (41no) shared 81 to guide the Welshmen home.
"It doesn't get too much better than that," said Allenby, "we've been wanting to play like that all season.
"We've basically had the batsmen win us the games when we've won them.
"Tonight the bowlers have stepped up and done an amazing job, so full credit to all 11 players. It really was a team effort."
Glamorgan will next play North Group winners Lancashire at Old Trafford in the T20 Blast, on Friday 1 August.
