New Multi-Select quota based on least fill (percentages)

Hi all ... using the new multi-select quota tool. Fine piece of kit. BUT least fill based on percentages doesn't seem to be working as expected.

Settings here:

Begin Unverified Perl
# ****************************************************************************************************
# Parameters
# ****************************************************************************************************
my $quotaBaseName = 'Brand';
my $passInBaseName = 'QuotaHelper';

# The number of quota questions, and the maximum number of choices to make for any respondent
my $numberOfQuotas = 2;

# The number of choices to make for the current respondent, between 0 and $numberOfQuotas
my $numberOfChoices = 2;

# Order to check cells for membership
#	1	-	Sequentially
#	2	-	Least fill (percentages)
#	3	-	Least fill (counts)
#	4	-	Random
my $membershipOrder = 2;

# Settings for each quota cell
# 	"limit"		-	The maximum number of respondents for this cell (may be exceeded).
#	"qualify"	-	The logic controlling whether the current respondent should qualify for this cell.  The default "return 1" will have all respondents qualify.
my %quotaCells = (
	1 => {
		limit => 300,
		qualify => sub { return LISTHASPARENTMEMBER("C4forC99",1); }
	},
	2 => {
		limit => 100,
		qualify => sub { return LISTHASPARENTMEMBER("C4forC99",2); }
	},
	3 => {
		limit => 100,
		qualify => sub { return LISTHASPARENTMEMBER("C4forC99",3); }
	},
