You stated that you were leaning toward the Chaldean system as being more accurate. So we can look at the Chaldean system for your name... Lukas gives a 15/6  
15.
This is a number of occult significance, of magic and mystery; but as a rule it does not represent the higher side of occultism, its meaning being that the persons represented by it will use every art of magic they can to carry out their purpose. If associated with a good or fortunate single number, it can be very lucky and power­ful, but if associated with one of the peculiar numbers, such as a 4 or an 8, the person it represents will not hesitate to use any sort of art, or even ''black-magic," to gain what he or she desires.  It  is peculiarly associated with "good talkers," often with elo­quence, gifts of music and art and a dramatic personality, combin­ed with a certain voluptuous temperament and strong personal magnetism. For obtaining money, gifts, and favours from others it is a fortunate number.

Majerik gives us a 16/7
16.  

This number has a most peculiar occult symbolism. It is pictured by "a Tower Struck by Lightning from which a man is falling with a Crown on his head." It is also called "the Shattered Citadel".
It gives warning of some strange fatality awaiting one, also danger of accidents and defeat of one's plans. If it appears as a "compound" number relating to the future, it is a warning sign that should be carefully noted and plans made in advance in the endeavour to avert its fatalistic tendency.
(You can research the tower card in tarot to gain further understanding of this)...And the karmic debt number 16... relates a lot to the fall of the ego and continual times of renewal.

Your full name gives a 31/4 vibration
31.

This number is very similar to the preceding one, except that the person it represents is even more self-contacted, lonely, and isolated from his fellows. It is not a fortunate number from a worldly or material standpoint.
30.  This is a number of thoughtful deduction, retrospection, and mental superiority over one's fellows, but as it seems to belong completely to the mental plane. The persons it represents, are likely to put all material things on one side — not because they have to, but because they wish to do so. For this reason it is neither for­tunate nor unfortunate, for either depends on the mental outlook of the person it represents. It can be all powerful, but it is just as often indifferent according to the will or desire of the person.
