Well, it may be OEP, looks like OEP. (BTW, I wrote to you in PM about 1 month earlier about OEP and import table. I don't remember exact addresses now.) As I remember there is only 1 jump that should be patched to get clear import table, but I'm not sure, it was too long ago.
Well, good import entry usually looks like xx xx xx 77 or xx xx xx 7c, others are usually bad (invalid or edited by Arma). To find the beginning I usually look for zero entries (00 00 00 00) or many invalid entries. Anyway, when entering addresses in ImpRec it's not essential to enter precise address of beginning, you can substract for example 100 to be sure, that beginning is in the interval.
