I think the date of funds conversion is not a solid indication of anything.
But if you analyze the trend here, majority got nominations after their funds were converted.
In my case, Date of Conversion is December 2015. They then requested further supporting documents on April 2016.
A few days after submission, i got nominated.
You'll get your nomination soon. Keep the faith Kabayan!
