In the last 9 months (with a short break from mining) I have done over 20,000 drops and I am still waiting for a HOF. My TT return during this period is always around 70%.
70% doesn't sound completely out of line for that many drops. You're going to get variation around that 90% average.
Your are burning some extra PED though using the F-105, which is one of the more inefficient finders out there. An F-212 (L) or eMINE FS (L) will both go deeper and cost less per drop (even after MU) than an F-105. It might be different if you are using enhancers, but I tend to stay away from them for finders at least.
Otherwise, just try changing your areas up a bit. It could be you're in an area that gets mined by other people a bit.
buy terramaster 6..
Since The Change, it is difficult to hof planetside unamped For Sure..
Good luck on the field.
if there is area with igni(140%) and terru(108%) why go deep if you get more terru that way?
Extra ped burned with F-105 decay doesnt matter because claim tt size is proportional to decay+probes
I'd be curious to see some actual numbers on that. It's pretty well established that this is the general setup for probes+amp decay, but I haven't seen anyone demonstrate that finder decay actually affects claim size.
