So this is really rough, and I have no idea where you got your death points; I applied 3 "small deaths" (less than 2K) to two of your highest level scores and the third randomly at the end, using Wes' pace app: here is your rough estimate at the end of each level...
L4 120K
L5 178K (~56K level + small death) 1,080,400
L6 231K----------------------------- 1,051,500
L7 290K (~57K level + small death) 1,068,400
L8 343K -----------------------------1,058,200
L9 400K------------------------------1,065,000
L10 453K ----------------------------1,058,200
L11 509K ----------------------------1,059,900
L12 568K ----------------------------1,068,400
L13 621K ----------------------------1,063,300
L14 677K ----------------------------1,065,000
L15 725K ----------------------------1,053,100
L16 781K (~54K + small death)----- 1,054,700
L17-4 FAIL 812K
The places I chose (randomly) to enter death points, will obviously skew things somewhat, but you should get the general picture; keep going good
