as you have more slices, you need to split your deposit up more. However, in order for the pie to autoinvest on your behalf you need to have a minimum amount of funds according to the smallest slice in your pie.
I will use £GBP as that is my currency, but the minimum deposit for a slice is 20p. so if your slice is 0.5% that would mean your Pie must invest in that slice at least 20p
0.5% = 20p
1% = 40p
100% = £40
so if I convert the currency
0.5% = 1PLN
1% = 2PLN
100% = 200PLN
that is the highest your minimum deposit will become.
so you need to look at what percentage your smallest slice is, treat that as 1PLN and multiply until you know what 100% is and you will find out the minimum deposit for your current configuration. As you change your pie allocation your minimum will change accordingly.
