Loughborough Students edged a step closer to securing their National One status as they overturned a 15-3 deficit to beat rivals Tynedale 19-18.
Students started the day 12 points clear of the bottom three, but Macclesfield are only in the final relegation position because of a deduction.
Macclesfield's form is anything but that of a struggler as a 17-15 verdict at Richmond represented a fourth success on the trot.
Fourth-bottom Wharfedale also landed a crucial 22-8 win against Cinderford.
Tynedale could have leapfrogged Students and dragged them back into a relegation scrap, so the pressure was on to deliver a result.
Loughborough duly delivered and moved seven points clear of their rivals while maintaining their cushion over Macclesfield.
Fly-half Stuart Hall kicked an early penalty for Students but Tynedale were 8-3 ahead after 23 minutes as Dave Cherry crossed and Matthew Outsen slotted a penalty.
Students hooker John Collister saw yellow and Tynedale took advantage as Ben Frankland scored their second try. Outsen converted to put the visitors in control.
Hall reduced the deficit with a second penalty before half-time and two more three-pointers brought them back to 15-12 down after 48 minutes.
Students piled on the pressure and that led to Frankland being sent to the sin-bin.
Tynedale survived that 10-minute period but fell behind as prop Tom Crozier crossed and Hall converted with 13 minutes to go.
George Cullen kicked a 71st-minute penalty to narrow the gap to a solitary point but Students held firm to take the spoils.
Leicester Lions knew they were in for a tough afternoon at National Two North leaders Stourbridge.
Their opponents had lost just two games all season and Lions had only a Jon Boden penalty to show for their efforts in a 41-3 setback.

Dave Torr scored and Warren Coles slotted the winning penalty.
Hinckley bounced back from a narrow derby defeat at Nuneaton to register a single-point victory. They beat Longton 19-18 at Leicester Road thanks to tries from Phil Brocken and Ben Ashfield, and penalties from Josh Smith (2) and Ryan Oakes.
The game of the day saw third-placed South Leicester host champions-elect Sutton Coldfield, and it was the visitors who won 28-6, despite two Mark Lord penalties.
