You only need to dynamically load the repeater and not the sub fields.
// set load value for repeater
$repeater = array(
// a nested array for each row
array(
// a value for each subfield
// use field keys rather than field names
'field_0123456789abc' => 'value for field',
'field_0123456789abd' => 'value for field',
// etc...
)
);
